-# There are two options in making libm at fdlibm compile time:
-# _IEEE_LIBM --- IEEE libm; smaller, and somewhat faster
-# _MULTI_LIBM --- Support multi-standard at runtime by
-# imposing wrapper functions defined in
-# fdlibm.h:
-# _IEEE_MODE -- IEEE
-# _XOPEN_MODE -- X/OPEN
-# _POSIX_MODE -- POSIX/ANSI
-# _SVID3_MODE -- SVID
-#
-# Here is how to set up CFLAGS to create the desired libm at
-# compile time:
-#
-# CFLAGS = -D_IEEE_LIBM ... IEEE libm (recommended)
-# CFLAGS = -D_SVID3_MODE ... Multi-standard supported
-# libm with SVID as the
-# default standard
-# CFLAGS = -D_XOPEN_MODE ... Multi-standard supported
-# libm with XOPEN as the
-# default standard
-# CFLAGS = -D_POSIX_MODE ... Multi-standard supported
-# libm with POSIX as the
-# default standard
-# CFLAGS = ... Multi-standard supported
-# libm with IEEE as the
-# default standard
-#
-# NOTE: if scalb's second arguement is an int, then one must
-# define _SCALB_INT in CFLAGS. The default prototype of scalb
-# is double scalb(double, double)

-/* __ieee754_exp(x)
- * Returns the exponential of x.
- *
- * Method
- * 1. Argument reduction:
- * Reduce x to an r so that |r| <= 0.5*ln2 ~ 0.34658.
- * Given x, find r and integer k such that
- *
- * x = k*ln2 + r, |r| <= 0.5*ln2.
- *
- * Here r will be represented as r = hi-lo for better
- * accuracy.
- *
- * 2. Approximation of exp(r) by a special rational function on
- * the interval [0,0.34658]:
- * Write
- * R(r**2) = r*(exp(r)+1)/(exp(r)-1) = 2 + r*r/6 - r**4/360 + ...
- * We use a special Reme algorithm on [0,0.34658] to generate
- * a polynomial of degree 5 to approximate R. The maximum error
- * of this polynomial approximation is bounded by 2**-59. In
- * other words,
- * R(z) ~ 2.0 + P1*z + P2*z**2 + P3*z**3 + P4*z**4 + P5*z**5
- * (where z=r*r, and the values of P1 to P5 are listed below)
- * and
- * | 5 | -59
- * | 2.0+P1*z+...+P5*z - R(z) | <= 2
- * | |
- * The computation of exp(r) thus becomes
- * 2*r
- * exp(r) = 1 + -------
- * R - r
- * r*R1(r)
- * = 1 + r + ----------- (for better accuracy)
- * 2 - R1(r)
- * where
- * 2 4 10
- * R1(r) = r - (P1*r + P2*r + ... + P5*r ).
- *
- * 3. Scale back to obtain exp(x):
- * From step 1, we have
- * exp(x) = 2^k * exp(r)
- *
- * Special cases:
- * exp(INF) is INF, exp(NaN) is NaN;
- * exp(-INF) is 0, and
- * for finite argument, only exp(0)=1 is exact.
- *
- * Accuracy:
- * according to an error analysis, the error is always less than
- * 1 ulp (unit in the last place).
- *
- * Misc. info.
- * For IEEE double
- * if x > 7.09782712893383973096e+02 then exp(x) overflow
- * if x < -7.45133219101941108420e+02 then exp(x) underflow
- *
- * Constants:
- * The hexadecimal values are the intended ones for the following
- * constants. The decimal values may be used, provided that the
- * compiler will convert from decimal to binary accurately enough
- * to produce the hexadecimal values shown.

- * Method :

- *
- * So, compute sqrt(x*x+y*y) with some care as

- *
- * Assume x>y>0;
- * (if possible, set rounding to round-to-nearest)

- * where t1 = 2x with lower 32 bits cleared, t2 = 2x-t1,
- * y1= y with lower 32 bits chopped, y2 = y-y1.
- *
- * NOTE: scaling may be necessary if some argument is too

- *
- * Special cases:
- * hypot(x,y) is INF if x or y is +INF or -INF; else

- *
- * Accuracy:

- * Bessel function of the first and second kinds of order zero.
- * Method -- j0(x):
- * 1. For tiny x, we use j0(x) = 1 - x^2/4 + x^4/64 - ...
- * 2. Reduce x to |x| since j0(x)=j0(-x), and
- * for x in (0,2)
- * j0(x) = 1-z/4+ z^2*R0/S0, where z = x*x;
- * (precision: |j0-1+z/4-z^2R0/S0 |<2**-63.67 )
- * for x in (2,inf)
- * j0(x) = sqrt(2/(pi*x))*(p0(x)*cos(x0)-q0(x)*sin(x0))
- * where x0 = x-pi/4. It is better to compute sin(x0),cos(x0)
- * as follow:
- * cos(x0) = cos(x)cos(pi/4)+sin(x)sin(pi/4)
- * = 1/sqrt(2) * (cos(x) + sin(x))
- * sin(x0) = sin(x)cos(pi/4)-cos(x)sin(pi/4)
- * = 1/sqrt(2) * (sin(x) - cos(x))
- * (To avoid cancellation, use
- * sin(x) +- cos(x) = -cos(2x)/(sin(x) -+ cos(x))
- * to compute the worse one.)
- *
- * 3 Special cases
- * j0(nan)= nan
- * j0(0) = 1
- * j0(inf) = 0
- *
- * Method -- y0(x):
- * 1. For x<2.
- * Since
- * y0(x) = 2/pi*(j0(x)*(ln(x/2)+Euler) + x^2/4 - ...)
- * therefore y0(x)-2/pi*j0(x)*ln(x) is an even function.
- * We use the following function to approximate y0,
- * y0(x) = U(z)/V(z) + (2/pi)*(j0(x)*ln(x)), z= x^2
- * where
- * U(z) = u00 + u01*z + ... + u06*z^6
- * V(z) = 1 + v01*z + ... + v04*z^4
- * with absolute approximation error bounded by 2**-72.
- * Note: For tiny x, U/V = u0 and j0(x)~1, hence
- * y0(tiny) = u0 + (2/pi)*ln(tiny), (choose tiny<2**-27)
- * 2. For x>=2.
- * y0(x) = sqrt(2/(pi*x))*(p0(x)*cos(x0)+q0(x)*sin(x0))
- * where x0 = x-pi/4. It is better to compute sin(x0),cos(x0)
- * by the method mentioned above.
- * 3. Special cases: y0(0)=-inf, y0(x<0)=NaN, y0(inf)=0.

-/* __ieee754_j1(x), __ieee754_y1(x)
- * Bessel function of the first and second kinds of order zero.
- * Method -- j1(x):
- * 1. For tiny x, we use j1(x) = x/2 - x^3/16 + x^5/384 - ...
- * 2. Reduce x to |x| since j1(x)=-j1(-x), and
- * for x in (0,2)
- * j1(x) = x/2 + x*z*R0/S0, where z = x*x;
- * (precision: |j1/x - 1/2 - R0/S0 |<2**-61.51 )
- * for x in (2,inf)
- * j1(x) = sqrt(2/(pi*x))*(p1(x)*cos(x1)-q1(x)*sin(x1))
- * y1(x) = sqrt(2/(pi*x))*(p1(x)*sin(x1)+q1(x)*cos(x1))
- * where x1 = x-3*pi/4. It is better to compute sin(x1),cos(x1)
- * as follow:
- * cos(x1) = cos(x)cos(3pi/4)+sin(x)sin(3pi/4)
- * = 1/sqrt(2) * (sin(x) - cos(x))
- * sin(x1) = sin(x)cos(3pi/4)-cos(x)sin(3pi/4)
- * = -1/sqrt(2) * (sin(x) + cos(x))
- * (To avoid cancellation, use
- * sin(x) +- cos(x) = -cos(2x)/(sin(x) -+ cos(x))
- * to compute the worse one.)
- *
- * 3 Special cases
- * j1(nan)= nan
- * j1(0) = 0
- * j1(inf) = 0
- *
- * Method -- y1(x):
- * 1. screen out x<=0 cases: y1(0)=-inf, y1(x<0)=NaN
- * 2. For x<2.
- * Since
- * y1(x) = 2/pi*(j1(x)*(ln(x/2)+Euler)-1/x-x/2+5/64*x^3-...)
- * therefore y1(x)-2/pi*j1(x)*ln(x)-1/x is an odd function.
- * We use the following function to approximate y1,
- * y1(x) = x*U(z)/V(z) + (2/pi)*(j1(x)*ln(x)-1/x), z= x^2
- * where for x in [0,2] (abs err less than 2**-65.89)
- * U(z) = U0[0] + U0[1]*z + ... + U0[4]*z^4
- * V(z) = 1 + v0[0]*z + ... + v0[4]*z^5
- * Note: For tiny x, 1/x dominate y1 and hence
- * y1(tiny) = -2/pi/tiny, (choose tiny<2**-54)
- * 3. For x>=2.
- * y1(x) = sqrt(2/(pi*x))*(p1(x)*sin(x1)+q1(x)*cos(x1))
- * where x1 = x-3*pi/4. It is better to compute sin(x1),cos(x1)
- * by method mentioned above.

-/* __ieee754_lgamma_r(x, signgamp)
- * Reentrant version of the logarithm of the Gamma function
- * with user provide pointer for the sign of Gamma(x).
- *
- * Method:
- * 1. Argument Reduction for 0 < x <= 8
- * Since gamma(1+s)=s*gamma(s), for x in [0,8], we may
- * reduce x to a number in [1.5,2.5] by
- * lgamma(1+s) = log(s) + lgamma(s)
- * for example,
- * lgamma(7.3) = log(6.3) + lgamma(6.3)
- * = log(6.3*5.3) + lgamma(5.3)
- * = log(6.3*5.3*4.3*3.3*2.3) + lgamma(2.3)
- * 2. Polynomial approximation of lgamma around its
- * minimun ymin=1.461632144968362245 to maintain monotonicity.
- * On [ymin-0.23, ymin+0.27] (i.e., [1.23164,1.73163]), use
- * Let z = x-ymin;
- * lgamma(x) = -1.214862905358496078218 + z^2*poly(z)
- * where
- * poly(z) is a 14 degree polynomial.
- * 2. Rational approximation in the primary interval [2,3]
- * We use the following approximation:
- * s = x-2.0;
- * lgamma(x) = 0.5*s + s*P(s)/Q(s)
- * with accuracy
- * |P/Q - (lgamma(x)-0.5s)| < 2**-61.71
- * Our algorithms are based on the following observation
- *
- * zeta(2)-1 2 zeta(3)-1 3
- * lgamma(2+s) = s*(1-Euler) + --------- * s - --------- * s + ...
- * 2 3
- *
- * where Euler = 0.5771... is the Euler constant, which is very
- * close to 0.5.
- *
- * 3. For x>=8, we have
- * lgamma(x)~(x-0.5)log(x)-x+0.5*log(2pi)+1/(12x)-1/(360x**3)+....
- * (better formula:
- * lgamma(x)~(x-0.5)*(log(x)-1)-.5*(log(2pi)-1) + ...)
- * Let z = 1/x, then we approximation
- * f(z) = lgamma(x) - (x-0.5)(log(x)-1)
- * by
- * 3 5 11
- * w = w0 + w1*z + w2*z + w3*z + ... + w6*z
- * where
- * |w - f(z)| < 2**-58.74
- *
- * 4. For negative x, since (G is gamma function)
- * -x*G(-x)*G(x) = pi/sin(pi*x),
- * we have
- * G(x) = pi/(sin(pi*x)*(-x)*G(-x))
- * since G(-x) is positive, sign(G(x)) = sign(sin(pi*x)) for x<0
- * Hence, for x<0, signgam = sign(sin(pi*x)) and
- * lgamma(x) = log(|Gamma(x)|)
- * = log(pi/(|x*sin(pi*x)|)) - lgamma(-x);
- * Note: one should avoid compute pi*(-x) directly in the
- * computation of sin(pi*(-x)).
- *
- * 5. Special Cases
- * lgamma(2+s) ~ s*(1-Euler) for tiny s
- * lgamma(1)=lgamma(2)=0
- * lgamma(x) ~ -log(x) for tiny x
- * lgamma(0) = lgamma(inf) = inf
- * lgamma(-integer) = +-inf

-/* __ieee754_log(x)
- * Return the logrithm of x
- *
- * Method :
- * 1. Argument Reduction: find k and f such that
- * x = 2^k * (1+f),
- * where sqrt(2)/2 < 1+f < sqrt(2) .
- *
- * 2. Approximation of log(1+f).
- * Let s = f/(2+f) ; based on log(1+f) = log(1+s) - log(1-s)
- * = 2s + 2/3 s**3 + 2/5 s**5 + .....,
- * = 2s + s*R
- * We use a special Reme algorithm on [0,0.1716] to generate
- * a polynomial of degree 14 to approximate R The maximum error
- * of this polynomial approximation is bounded by 2**-58.45. In
- * other words,
- * 2 4 6 8 10 12 14
- * R(z) ~ Lg1*s +Lg2*s +Lg3*s +Lg4*s +Lg5*s +Lg6*s +Lg7*s
- * (the values of Lg1 to Lg7 are listed in the program)
- * and
- * | 2 14 | -58.45
- * | Lg1*s +...+Lg7*s - R(z) | <= 2
- * | |
- * Note that 2s = f - s*f = f - hfsq + s*hfsq, where hfsq = f*f/2.
- * In order to guarantee error in log below 1ulp, we compute log
- * by
- * log(1+f) = f - s*(f - R) (if f is not too large)
- * log(1+f) = f - (hfsq - s*(hfsq+R)). (better accuracy)
- *
- * 3. Finally, log(x) = k*ln2 + log(1+f).
- * = k*ln2_hi+(f-(hfsq-(s*(hfsq+R)+k*ln2_lo)))
- * Here ln2 is split into two floating point number:
- * ln2_hi + ln2_lo,
- * where n*ln2_hi is always exact for |n| < 2000.
- *
- * Special cases:
- * log(x) is NaN with signal if x < 0 (including -INF) ;
- * log(+INF) is +INF; log(0) is -INF with signal;
- * log(NaN) is that NaN with no signal.
- *
- * Accuracy:
- * according to an error analysis, the error is always less than
- * 1 ulp (unit in the last place).
- *
- * Constants:
- * The hexadecimal values are the intended ones for the following
- * constants. The decimal values may be used, provided that the
- * compiler will convert from decimal to binary accurately enough
- * to produce the hexadecimal values shown.

-/* __ieee754_sqrt(x)
- * Return correctly rounded sqrt.
- * ------------------------------------------
- * | Use the hardware sqrt if you have one |
- * ------------------------------------------
- * Method:
- * Bit by bit method using integer arithmetic. (Slow, but portable)
- * 1. Normalization
- * Scale x to y in [1,4) with even powers of 2:
- * find an integer k such that 1 <= (y=x*2^(2k)) < 4, then
- * sqrt(y) = 2^k * sqrt(x)
- * 2. Bit by bit computation
- * Let q = sqrt(y) truncated to i bit after binary point (q = 1),
- * i 0
- * i+1 2
- * s = 2*q , and y = 2 * ( y - q ). (1)
- * i i i i
- *
- * To compute q from q , one checks whether
- * i+1 i
- *
- * -(i+1) 2
- * (q + 2 ) <= y. (2)
- * i
- * -(i+1)
- * If (2) is false, then q = q ; otherwise q = q + 2 .
- * i+1 i i+1 i
- *
- * With some algebric manipulation, it is not difficult to see
- * that (2) is equivalent to
- * -(i+1)
- * s + 2 <= y (3)
- * i i
- *
- * The advantage of (3) is that s and y can be computed by
- * i i
- * the following recurrence formula:
- * if (3) is false
- *
- * s = s , y = y ; (4)
- * i+1 i i+1 i
- *
- * otherwise,
- * -i -(i+1)
- * s = s + 2 , y = y - s - 2 (5)
- * i+1 i i+1 i i
- *
- * One may easily use induction to prove (4) and (5).
- * Note. Since the left hand side of (3) contain only i+2 bits,
- * it does not necessary to do a full (53-bit) comparison
- * in (3).
- * 3. Final rounding
- * After generating the 53 bits result, we compute one more bit.
- * Together with the remainder, we can decide whether the
- * result is exact, bigger than 1/2ulp, or less than 1/2ulp
- * (it will never equal to 1/2ulp).
- * The rounding mode can be detected by checking whether
- * huge + tiny is equal to huge, and whether huge - tiny is
- * equal to huge for some floating point number "huge" and "tiny".
- *
- * Special cases:
- * sqrt(+-0) = +-0 ... exact
- * sqrt(inf) = inf
- * sqrt(-ve) = NaN ... with invalid signal
- * sqrt(NaN) = NaN ... with invalid signal for signaling NaN
- *
- * Other methods : see the appended file at the end of the program below.

-Other methods (use floating-point arithmetic)
--------------
-(This is a copy of a drafted paper by Prof W. Kahan
-and K.C. Ng, written in May, 1986)
-
- Two algorithms are given here to implement sqrt(x)
- (IEEE double precision arithmetic) in software.
- Both supply sqrt(x) correctly rounded. The first algorithm (in
- Section A) uses newton iterations and involves four divisions.
- The second one uses reciproot iterations to avoid division, but
- requires more multiplications. Both algorithms need the ability
- to chop results of arithmetic operations instead of round them,
- and the INEXACT flag to indicate when an arithmetic operation
- is executed exactly with no roundoff error, all part of the
- standard (IEEE 754-1985). The ability to perform shift, add,
- subtract and logical AND operations upon 32-bit words is needed
- too, though not part of the standard.
-
-A. sqrt(x) by Newton Iteration
-
- (1) Initial approximation
-
- Let x0 and x1 be the leading and the trailing 32-bit words of
- a floating point number x (in IEEE double format) respectively

- By performing shifts and subtracts on x0 and x1 (both regarded
- as integers), we obtain an 8-bit approximation of sqrt(x) as
- follows.
-
- k := (x0>>1) + 0x1ff80000;
- y0 := k - T1[31&(k>>15)]. ... y ~ sqrt(x) to 8 bits
- Here k is a 32-bit integer and T1[] is an integer array containing
- correction terms. Now magically the floating value of y (y's
- leading 32-bit word is y0, the value of its trailing word is 0)
- approximates sqrt(x) to almost 8-bit.
-
- Value of T1:
- static int T1[32]= {
- 0, 1024, 3062, 5746, 9193, 13348, 18162, 23592,
- 29598, 36145, 43202, 50740, 58733, 67158, 75992, 85215,
- 83599, 71378, 60428, 50647, 41945, 34246, 27478, 21581,
- 16499, 12183, 8588, 5674, 3403, 1742, 661, 130,};
-
- (2) Iterative refinement
-
- Apply Heron's rule three times to y, we have y approximates
- sqrt(x) to within 1 ulp (Unit in the Last Place):
-
- y := (y+x/y)/2 ... almost 17 sig. bits
- y := (y+x/y)/2 ... almost 35 sig. bits
- y := y-(y-x/y)/2 ... within 1 ulp
-
-
- Remark 1.
- Another way to improve y to within 1 ulp is:
-
- y := (y+x/y) ... almost 17 sig. bits to 2*sqrt(x)
- y := y - 0x00100006 ... almost 18 sig. bits to sqrt(x)
-
- 2
- (x-y )*y
- y := y + 2* ---------- ...within 1 ulp
- 2
- 3y + x
-
-
- This formula has one division fewer than the one above; however,
- it requires more multiplications and additions. Also x must be
- scaled in advance to avoid spurious overflow in evaluating the
- expression 3y*y+x. Hence it is not recommended uless division
- is slow. If division is very slow, then one should use the
- reciproot algorithm given in section B.
-
- (3) Final adjustment
-
- By twiddling y's last bit it is possible to force y to be
- correctly rounded according to the prevailing rounding mode
- as follows. Let r and i be copies of the rounding mode and
- inexact flag before entering the square root program. Also we
- use the expression y+-ulp for the next representable floating
- numbers (up and down) of y. Note that y+-ulp = either fixed
- point y+-1, or multiply y by nextafter(1,+-inf) in chopped
- mode.
-
- I := FALSE; ... reset INEXACT flag I
- R := RZ; ... set rounding mode to round-toward-zero
- z := x/y; ... chopped quotient, possibly inexact
- If(not I) then { ... if the quotient is exact
- if(z=y) {
- I := i; ... restore inexact flag
- R := r; ... restore rounded mode
- return sqrt(x):=y.
- } else {
- z := z - ulp; ... special rounding
- }
- }
- i := TRUE; ... sqrt(x) is inexact
- If (r=RN) then z=z+ulp ... rounded-to-nearest
- If (r=RP) then { ... round-toward-+inf
- y = y+ulp; z=z+ulp;
- }
- y := y+z; ... chopped sum
- y0:=y0-0x00100000; ... y := y/2 is correctly rounded.
- I := i; ... restore inexact flag
- R := r; ... restore rounded mode
- return sqrt(x):=y.
-
- (4) Special cases
-
- Square root of +inf, +-0, or NaN is itself;
- Square root of a negative number is NaN with invalid signal.
-
-
-B. sqrt(x) by Reciproot Iteration
-
- (1) Initial approximation
-
- Let x0 and x1 be the leading and the trailing 32-bit words of
- a floating point number x (in IEEE double format) respectively
- (see section A). By performing shifs and subtracts on x0 and y0,
- we obtain a 7.8-bit approximation of 1/sqrt(x) as follows.
-
- k := 0x5fe80000 - (x0>>1);
- y0:= k - T2[63&(k>>14)]. ... y ~ 1/sqrt(x) to 7.8 bits
-
- Here k is a 32-bit integer and T2[] is an integer array
- containing correction terms. Now magically the floating
- value of y (y's leading 32-bit word is y0, the value of
- its trailing word y1 is set to zero) approximates 1/sqrt(x)
- to almost 7.8-bit.
-
- Value of T2:
- static int T2[64]= {
- 0x1500, 0x2ef8, 0x4d67, 0x6b02, 0x87be, 0xa395, 0xbe7a, 0xd866,
- 0xf14a, 0x1091b,0x11fcd,0x13552,0x14999,0x15c98,0x16e34,0x17e5f,
- 0x18d03,0x19a01,0x1a545,0x1ae8a,0x1b5c4,0x1bb01,0x1bfde,0x1c28d,
- 0x1c2de,0x1c0db,0x1ba73,0x1b11c,0x1a4b5,0x1953d,0x18266,0x16be0,
- 0x1683e,0x179d8,0x18a4d,0x19992,0x1a789,0x1b445,0x1bf61,0x1c989,
- 0x1d16d,0x1d77b,0x1dddf,0x1e2ad,0x1e5bf,0x1e6e8,0x1e654,0x1e3cd,
- 0x1df2a,0x1d635,0x1cb16,0x1be2c,0x1ae4e,0x19bde,0x1868e,0x16e2e,
- 0x1527f,0x1334a,0x11051,0xe951, 0xbe01, 0x8e0d, 0x5924, 0x1edd,};
-
- (2) Iterative refinement
-
- Apply Reciproot iteration three times to y and multiply the
- result by x to get an approximation z that matches sqrt(x)
- to about 1 ulp. To be exact, we will have
- -1ulp < sqrt(x)-z<1.0625ulp.
-
- ... set rounding mode to Round-to-nearest
- y := y*(1.5-0.5*x*y*y) ... almost 15 sig. bits to 1/sqrt(x)
- y := y*((1.5-2^-30)+0.5*x*y*y)... about 29 sig. bits to 1/sqrt(x)
- ... special arrangement for better accuracy
- z := x*y ... 29 bits to sqrt(x), with z*y<1
- z := z + 0.5*z*(1-z*y) ... about 1 ulp to sqrt(x)
-
- Remark 2. The constant 1.5-2^-30 is chosen to bias the error so that
- (a) the term z*y in the final iteration is always less than 1;
- (b) the error in the final result is biased upward so that
- -1 ulp < sqrt(x) - z < 1.0625 ulp
- instead of |sqrt(x)-z|<1.03125ulp.
-
- (3) Final adjustment
-
- By twiddling y's last bit it is possible to force y to be
- correctly rounded according to the prevailing rounding mode
- as follows. Let r and i be copies of the rounding mode and
- inexact flag before entering the square root program. Also we
- use the expression y+-ulp for the next representable floating
- numbers (up and down) of y. Note that y+-ulp = either fixed
- point y+-1, or multiply y by nextafter(1,+-inf) in chopped
- mode.
-
- R := RZ; ... set rounding mode to round-toward-zero
- switch(r) {
- case RN: ... round-to-nearest
- if(x<= z*(z-ulp)...chopped) z = z - ulp; else
- if(x<= z*(z+ulp)...chopped) z = z; else z = z+ulp;
- break;
- case RZ:case RM: ... round-to-zero or round-to--inf
- R:=RP; ... reset rounding mod to round-to-+inf
- if(x=(z+ulp)*(z+ulp) ...rounded up) z = z+ulp;
- break;
- case RP: ... round-to-+inf
- if(x>(z+ulp)*(z+ulp)...chopped) z = z+2*ulp; else
- if(x>z*z ...chopped) z = z+ulp;
- break;
- }
-
- Remark 3. The above comparisons can be done in fixed point. For
- example, to compare x and w=z*z chopped, it suffices to compare
- x1 and w1 (the trailing parts of x and w), regarding them as
- two's complement integers.
-
- ...Is z an exact square root?
- To determine whether z is an exact square root of x, let z1 be the
- trailing part of z, and also let x0 and x1 be the leading and
- trailing parts of x.
-
- If ((z1&0x03ffffff)!=0) ... not exact if trailing 26 bits of z!=0
- I := 1; ... Raise Inexact flag: z is not exact
- else {
- j := 1 - [(x0>>20)&1] ... j = logb(x) mod 2
- k := z1 >> 26; ... get z's 25-th and 26-th
- fraction bits
- I := i or (k&j) or ((k&(j+j+1))!=(x1&3));
- }
- R:= r ... restore rounded mode
- return sqrt(x):=z.
-
- If multiplication is cheaper then the foregoing red tape, the
- Inexact flag can be evaluated by
-
- I := i;
- I := (z*z!=x) or I.
-
- Note that z*z can overwrite I; this value must be sensed if it is
- True.
-
- Remark 4. If z*z = x exactly, then bit 25 to bit 0 of z1 must be
- zero.
-
- --------------------
- z1: | f2 |
- --------------------
- bit 31 bit 0
-
- Further more, bit 27 and 26 of z1, bit 0 and 1 of x1, and the odd
- or even of logb(x) have the following relations:
-
- -------------------------------------------------
- bit 27,26 of z1 bit 1,0 of x1 logb(x)
- -------------------------------------------------
- 00 00 odd and even
- 01 01 even
- 10 10 odd
- 10 00 even
- 11 01 even
- -------------------------------------------------
-
- (4) Special cases (see (4) of Section A).

- * __kernel_cos( x, y )
- * kernel cos function on [-pi/4, pi/4], pi/4 ~ 0.785398164
- * Input x is assumed to be bounded by ~pi/4 in magnitude.
- * Input y is the tail of x.
- *
- * Algorithm
- * 1. Since cos(-x) = cos(x), we need only to consider positive x.
- * 2. if x < 2^-27 (hx<0x3e400000 0), return 1 with inexact if x!=0.
- * 3. cos(x) is approximated by a polynomial of degree 14 on
- * [0,pi/4]
- * 4 14
- * cos(x) ~ 1 - x*x/2 + C1*x + ... + C6*x
- * where the remez error is
- *
- * | 2 4 6 8 10 12 14 | -58
- * |cos(x)-(1-.5*x +C1*x +C2*x +C3*x +C4*x +C5*x +C6*x )| <= 2
- * | |
- *
- * 4 6 8 10 12 14
- * 4. let r = C1*x +C2*x +C3*x +C4*x +C5*x +C6*x , then
- * cos(x) = 1 - x*x/2 + r
- * since cos(x+y) ~ cos(x) - sin(x)*y
- * ~ cos(x) - x*y,
- * a correction term is necessary in cos(x) and hence
- * cos(x+y) = 1 - (x*x/2 - (r - x*y))
- * For better accuracy when x > 0.3, let qx = |x|/4 with
- * the last 32 bits mask off, and if x > 0.78125, let qx = 0.28125.
- * Then
- * cos(x+y) = (1-qx) - ((x*x/2-qx) - (r-x*y)).
- * Note that 1-qx and (x*x/2-qx) is EXACT here, and the
- * magnitude of the latter is at least a quarter of x*x/2,
- * thus, reducing the rounding error in the subtraction.

- * __kernel_rem_pio2(x,y,e0,nx,prec,ipio2)
- * double x[],y[]; int e0,nx,prec; int ipio2[];
- *
- * __kernel_rem_pio2 return the last three digits of N with
- * y = x - N*pi/2
- * so that |y| < pi/2.
- *
- * The method is to compute the integer (mod 8) and fraction parts of
- * (2/pi)*x without doing the full multiplication. In general we
- * skip the part of the product that are known to be a huge integer (
- * more accurately, = 0 mod 8 ). Thus the number of operations are
- * independent of the exponent of the input.
- *
- * (2/pi) is represented by an array of 24-bit integers in ipio2[].
- *
- * Input parameters:
- * x[] The input value (must be positive) is broken into nx
- * pieces of 24-bit integers in double precision format.
- * x[i] will be the i-th 24 bit of x. The scaled exponent
- * of x[0] is given in input parameter e0 (i.e., x[0]*2^e0
- * match x's up to 24 bits.
- *
- * Example of breaking a double positive z into x[0]+x[1]+x[2]:
- * e0 = ilogb(z)-23
- * z = scalbn(z,-e0)
- * for i = 0,1,2
- * x[i] = floor(z)
- * z = (z-x[i])*2**24
- *
- *
- * y[] ouput result in an array of double precision numbers.
- * The dimension of y[] is:
- * 24-bit precision 1
- * 53-bit precision 2
- * 64-bit precision 2
- * 113-bit precision 3
- * The actual value is the sum of them. Thus for 113-bit
- * precison, one may have to do something like:
- *
- * long double t,w,r_head, r_tail;
- * t = (long double)y[2] + (long double)y[1];
- * w = (long double)y[0];
- * r_head = t+w;
- * r_tail = w - (r_head - t);
- *
- * e0 The exponent of x[0]
- *
- * nx dimension of x[]
- *
- * prec an integer indicating the precision:
- * 0 24 bits (single)
- * 1 53 bits (double)
- * 2 64 bits (extended)
- * 3 113 bits (quad)
- *
- * ipio2[]
- * integer array, contains the (24*i)-th to (24*i+23)-th
- * bit of 2/pi after binary point. The corresponding
- * floating value is
- *
- * ipio2[i] * 2^(-24(i+1)).
- *
- * External function:
- * double scalbn(), floor();
- *
- *
- * Here is the description of some local variables:
- *
- * jk jk+1 is the initial number of terms of ipio2[] needed
- * in the computation. The recommended value is 2,3,4,
- * 6 for single, double, extended,and quad.
- *
- * jz local integer variable indicating the number of
- * terms of ipio2[] used.
- *
- * jx nx - 1
- *
- * jv index for pointing to the suitable ipio2[] for the
- * computation. In general, we want
- * ( 2^e0*x[0] * ipio2[jv-1]*2^(-24jv) )/8
- * is an integer. Thus
- * e0-3-24*jv >= 0 or (e0-3)/24 >= jv
- * Hence jv = max(0,(e0-3)/24).
- *
- * jp jp+1 is the number of terms in PIo2[] needed, jp = jk.
- *
- * q[] double array with integral value, representing the
- * 24-bits chunk of the product of x and 2/pi.
- *
- * q0 the corresponding exponent of q[0]. Note that the
- * exponent for q[i] would be q0-24*i.
- *
- * PIo2[] double precision array, obtained by cutting pi/2
- * into 24 bits chunks.
- *
- * f[] ipio2[] in floating point
- *
- * iq[] integer array by breaking up q[] in 24-bits chunk.
- *
- * fq[] final product of x*(2/pi) in fq[0],..,fq[jk]
- *
- * ih integer. If >0 it indicates q[] is >= 0.5, hence
- * it also indicates the *sign* of the result.
- *

-/* __kernel_tan( x, y, k )
- * kernel tan function on [-pi/4, pi/4], pi/4 ~ 0.7854
- * Input x is assumed to be bounded by ~pi/4 in magnitude.
- * Input y is the tail of x.
- * Input k indicates whether tan (if k=1) or
- * -1/tan (if k= -1) is returned.
- *
- * Algorithm
- * 1. Since tan(-x) = -tan(x), we need only to consider positive x.
- * 2. if x < 2^-28 (hx<0x3e300000 0), return x with inexact if x!=0.
- * 3. tan(x) is approximated by a odd polynomial of degree 27 on
- * [0,0.67434]
- * 3 27
- * tan(x) ~ x + T1*x + ... + T13*x
- * where
- *
- * |tan(x) 2 4 26 | -59.2
- * |----- - (1+T1*x +T2*x +.... +T13*x )| <= 2
- * | x |
- *
- * Note: tan(x+y) = tan(x) + tan'(x)*y
- * ~ tan(x) + (1+x*x)*y
- * Therefore, for better accuracy in computing tan(x+y), let
- * 3 2 2 2 2
- * r = x *(T2+x *(T3+x *(...+x *(T12+x *T13))))
- * then
- * 3 2
- * tan(x+y) = x + (T1*x + (x *(r+y)+y))
- *
- * 4. For x in [0.67434,pi/4], let y = pi/4 - x, then
- * tan(x) = tan(pi/4-y) = (1-tan(y))/(1+tan(y))
- * = 1 - 2*(tan(y) - (tan(y)^2)/(1+tan(y)))

- * 0
- *
- * erfc(x) = 1-erf(x)
- * Note that
- * erf(-x) = -erf(x)
- * erfc(-x) = 2 - erfc(x)
- *
- * Method:
- * 1. For |x| in [0, 0.84375]
- * erf(x) = x + x*R(x^2)
- * erfc(x) = 1 - erf(x) if x in [-.84375,0.25]
- * = 0.5 + ((0.5-x)-x*R) if x in [0.25,0.84375]
- * where R = P/Q where P is an odd poly of degree 8 and
- * Q is an odd poly of degree 10.
- * -57.90
- * | R - (erf(x)-x)/x | <= 2
- *
- *
- * Remark. The formula is derived by noting
- * erf(x) = (2/sqrt(pi))*(x - x^3/3 + x^5/10 - x^7/42 + ....)
- * and that
- * 2/sqrt(pi) = 1.128379167095512573896158903121545171688
- * is close to one. The interval is chosen because the fix

- * near 0.6174), and by some experiment, 0.84375 is chosen to
- * guarantee the error is less than one ulp for erf.
- *
- * 2. For |x| in [0.84375,1.25], let s = |x| - 1, and
- * c = 0.84506291151 rounded to single (24 bits)

- * |P1/Q1 - (erf(|x|)-c)| <= 2**-59.06
- * Remark: here we use the taylor series expansion at x=1.
- * erf(1+s) = erf(1) + s*Poly(s)
- * = 0.845.. + P1(s)/Q1(s)
- * That is, we use rational approximation to approximate
- * erf(1+s) - (c = (single)0.84506291151)
- * Note that |P1/Q1|< 0.078 for x in [0.84375,1.25]
- * where
- * P1(s) = degree 6 poly in s
- * Q1(s) = degree 6 poly in s
- *
- * 3. For x in [1.25,1/0.35(~2.857143)],
- * erfc(x) = (1/x)*exp(-x*x-0.5625+R1/S1)
- * erf(x) = 1 - erfc(x)
- * where
- * R1(z) = degree 7 poly in z, (z=1/x^2)
- * S1(z) = degree 8 poly in z
- *
- * 4. For x in [1/0.35,28]
- * erfc(x) = (1/x)*exp(-x*x-0.5625+R2/S2) if x > 0

-/* expm1(x)
- * Returns exp(x)-1, the exponential of x minus 1.
- *
- * Method
- * 1. Argument reduction:
- * Given x, find r and integer k such that
- *
- * x = k*ln2 + r, |r| <= 0.5*ln2 ~ 0.34658
- *
- * Here a correction term c will be computed to compensate
- * the error in r when rounded to a floating-point number.
- *
- * 2. Approximating expm1(r) by a special rational function on
- * the interval [0,0.34658]:
- * Since
- * r*(exp(r)+1)/(exp(r)-1) = 2+ r^2/6 - r^4/360 + ...
- * we define R1(r*r) by
- * r*(exp(r)+1)/(exp(r)-1) = 2+ r^2/6 * R1(r*r)
- * That is,
- * R1(r**2) = 6/r *((exp(r)+1)/(exp(r)-1) - 2/r)
- * = 6/r * ( 1 + 2.0*(1/(exp(r)-1) - 1/r))
- * = 1 - r^2/60 + r^4/2520 - r^6/100800 + ...
- * We use a special Reme algorithm on [0,0.347] to generate
- * a polynomial of degree 5 in r*r to approximate R1. The
- * maximum error of this polynomial approximation is bounded
- * by 2**-61. In other words,
- * R1(z) ~ 1.0 + Q1*z + Q2*z**2 + Q3*z**3 + Q4*z**4 + Q5*z**5
- * where Q1 = -1.6666666666666567384E-2,
- * Q2 = 3.9682539681370365873E-4,
- * Q3 = -9.9206344733435987357E-6,
- * Q4 = 2.5051361420808517002E-7,
- * Q5 = -6.2843505682382617102E-9;
- * (where z=r*r, and the values of Q1 to Q5 are listed below)
- * with error bounded by
- * | 5 | -61
- * | 1.0+Q1*z+...+Q5*z - R1(z) | <= 2
- * | |
- *
- * expm1(r) = exp(r)-1 is then computed by the following
- * specific way which minimize the accumulation rounding error:
- * 2 3
- * r r [ 3 - (R1 + R1*r/2) ]
- * expm1(r) = r + --- + --- * [--------------------]
- * 2 2 [ 6 - r*(3 - R1*r/2) ]
- *
- * To compensate the error in the argument reduction, we use
- * expm1(r+c) = expm1(r) + c + expm1(r)*c
- * ~ expm1(r) + c + r*c
- * Thus c+r*c will be added in as the correction terms for
- * expm1(r+c). Now rearrange the term to avoid optimization
- * screw up:
- * ( 2 2 )
- * ({ ( r [ R1 - (3 - R1*r/2) ] ) } r )
- * expm1(r+c)~r - ({r*(--- * [--------------------]-c)-c} - --- )
- * ({ ( 2 [ 6 - r*(3 - R1*r/2) ] ) } 2 )
- * ( )
- *
- * = r - E
- * 3. Scale back to obtain expm1(x):
- * From step 1, we have
- * expm1(x) = either 2^k*[expm1(r)+1] - 1
- * = or 2^k*[expm1(r) + (1-2^-k)]
- * 4. Implementation notes:
- * (A). To save one multiplication, we scale the coefficient Qi
- * to Qi*2^i, and replace z by (x^2)/2.
- * (B). To achieve maximum accuracy, we compute expm1(x) by
- * (i) if x < -56*ln2, return -1.0, (raise inexact if x!=inf)
- * (ii) if k=0, return r-E
- * (iii) if k=-1, return 0.5*(r-E)-0.5
- * (iv) if k=1 if r < -0.25, return 2*((r+0.5)- E)
- * else return 1.0+2.0*(r-E);
- * (v) if (k<-2||k>56) return 2^k(1-(E-r)) - 1 (or exp(x)-1)
- * (vi) if k <= 20, return 2^k((1-2^-k)-(E-r)), else
- * (vii) return 2^k(1-((E+2^-k)-r))
- *
- * Special cases:
- * expm1(INF) is INF, expm1(NaN) is NaN;
- * expm1(-INF) is -1, and
- * for finite argument, only expm1(0)=0 is exact.
- *
- * Accuracy:
- * according to an error analysis, the error is always less than
- * 1 ulp (unit in the last place).
- *
- * Misc. info.
- * For IEEE double
- * if x > 7.09782712893383973096e+02 then expm1(x) overflow
- *
- * Constants:
- * The hexadecimal values are the intended ones for the following
- * constants. The decimal values may be used, provided that the
- * compiler will convert from decimal to binary accurately enough
- * to produce the hexadecimal values shown.

-/* double log1p(double x)
- *
- * Method :
- * 1. Argument Reduction: find k and f such that
- * 1+x = 2^k * (1+f),
- * where sqrt(2)/2 < 1+f < sqrt(2) .
- *
- * Note. If k=0, then f=x is exact. However, if k!=0, then f
- * may not be representable exactly. In that case, a correction
- * term is need. Let u=1+x rounded. Let c = (1+x)-u, then
- * log(1+x) - log(u) ~ c/u. Thus, we proceed to compute log(u),
- * and add back the correction term c/u.
- * (Note: when x > 2**53, one can simply return log(x))
- *
- * 2. Approximation of log1p(f).
- * Let s = f/(2+f) ; based on log(1+f) = log(1+s) - log(1-s)
- * = 2s + 2/3 s**3 + 2/5 s**5 + .....,
- * = 2s + s*R
- * We use a special Reme algorithm on [0,0.1716] to generate
- * a polynomial of degree 14 to approximate R The maximum error
- * of this polynomial approximation is bounded by 2**-58.45. In
- * other words,
- * 2 4 6 8 10 12 14
- * R(z) ~ Lp1*s +Lp2*s +Lp3*s +Lp4*s +Lp5*s +Lp6*s +Lp7*s
- * (the values of Lp1 to Lp7 are listed in the program)
- * and
- * | 2 14 | -58.45
- * | Lp1*s +...+Lp7*s - R(z) | <= 2
- * | |
- * Note that 2s = f - s*f = f - hfsq + s*hfsq, where hfsq = f*f/2.
- * In order to guarantee error in log below 1ulp, we compute log
- * by
- * log1p(f) = f - (hfsq - s*(hfsq+R)).
- *
- * 3. Finally, log1p(x) = k*ln2 + log1p(f).
- * = k*ln2_hi+(f-(hfsq-(s*(hfsq+R)+k*ln2_lo)))
- * Here ln2 is split into two floating point number:
- * ln2_hi + ln2_lo,
- * where n*ln2_hi is always exact for |n| < 2000.
- *
- * Special cases:
- * log1p(x) is NaN with signal if x < -1 (including -INF) ;
- * log1p(+INF) is +INF; log1p(-1) is -INF with signal;
- * log1p(NaN) is that NaN with no signal.
- *
- * Accuracy:
- * according to an error analysis, the error is always less than
- * 1 ulp (unit in the last place).
- *
- * Constants:
- * The hexadecimal values are the intended ones for the following
- * constants. The decimal values may be used, provided that the
- * compiler will convert from decimal to binary accurately enough
- * to produce the hexadecimal values shown.
- *
- * Note: Assuming log() return accurate answer, the following
- * algorithm can be used to compute log1p(x) to within a few ULP:
- *
- * u = 1+x;
- * if(u==1.0) return x ; else
- * return log(u)*(x/(u-1.0));
- *
- * See HP-15C Advanced Functions Handbook, p.193.
