Saves comitters' daily life by avoid #include-ing everything from
internal.h to make each file do so instead. This would significantly
speed up incremental builds.
We take the following inclusion order in this changeset:
1. "ruby/config.h", where _GNU_SOURCE is defined (must be the very
first thing among everything).
2. RUBY_EXTCONF_H if any.
3. Standard C headers, sorted alphabetically.
4. Other system headers, maybe guarded by #ifdef
5. Everything else, sorted alphabetically.
Exceptions are those win32-related headers, which tend not be self-
containing (headers have inclusion order dependencies).
These functions are used from within a compilation unit so we can
make them static, for better binary size. This changeset reduces
the size of generated ruby binary from 26,590,128 bytes to
26,584,472 bytes on my macihne.
When searching for this constant, I landed on the correct page https://ruby-doc.org/core-2.6.4/Math.html however I was using CMD+f to search for "Euler" and did not find it. If we add the full name for this constant then it will be easier to search for and find.
* math.c (math_cbrt): refine the approximation result on boundary
values by an iteration of Newton-Raphson method.

It seems HUGE_VAL is already used. Why not eliminate INTINITY.
NAN is also float. That of double is called nan(). This is also
fixed.

* math.c (math_lgamma): check the argument before calling math
function `lgamma_r` for edge cases.

function `tgamma` for edge cases.

* configure.in: do not use buggy tgamma() of mingw.
* missing/tgamma.c (tgamma): merge fix for inifity from
ruby_tgamma. since msvcr120.dll and later have tgamma, this
implementation will not be used.

* math.c (tgamma): it seems that the implementaion of mswin has similar problem
with mingw.

* math.c: [DOC] mention possibly surprising behavior of Math.sqrt
due to floating point arithmetic; also refer to BigDecimal#sqrt.

is never used.

doesn't supply it.

* math.c (tanh): make faster by the extract form if three
hyperbolic functions are unavailable. [Feature #12647]
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@55799 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
because internal.h includes ruby.h, ruby.h includes win32.h, and
win32.h includes system's math.h.
this change is to get rid of a compiler warning (redefinition of
a macro) introduced at r55641.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@55662 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* math.c (get_double_rshift): extract bignum to double conversion
with bit offset.

* math.c (math_log1, math_log10): use common math constants
instead of math function calls.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@55641 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
returns positive infinity, in addition to lgamma_r(-0.0).
AIX returns an incorrect result of negative infinity.
* math.c (ruby_lgamma_r): handle +0.0, in addition to -0.0.

* math.c (ruby_lgamma_r): missing/lgamma_r.c is used on Windows,
since msvcrt does not provide it.
* missing/lgamma_r.c (lgamma_r): fix lgamma(-0.0).
