// In what follows, d is positive and is not a power of 2.
JS_ASSERT(d > 0 && (d & (d - 1)) != 0);
// Speeding up division by non power-of-2 constants is possible by
// calculating, during compilation, a value M such that high-order
// bits of M*n correspond to the result of the division. Formally,
// we compute values 0 <= M < 2^32 and 0 <= s < 31 such that
// (M * n) >> (32 + s) = floor(n/d) if n >= 0
// (M * n) >> (32 + s) = ceil(n/d) - 1 if n < 0.
// The original presentation of this technique appears in Hacker's
// Delight, a book by Henry S. Warren, Jr.. A proof of correctness
// for our version follows.
// Define p = 32 + s, M = ceil(2^p/d), and assume that s satisfies
// M - 2^p/d <= 2^(s+1)/d. (1)
// (Observe that s = FloorLog32(d) satisfies this, because in this
// case d <= 2^(s+1) and so the RHS of (1) is at least one). Then,
//
// a) If s <= FloorLog32(d), then M <= 2^32 - 1.
// Proof: Indeed, M is monotone in s and, for s = FloorLog32(d),
// the inequalities 2^31 > d >= 2^s + 1 readily imply
// 2^p / d = 2^p/(d - 1) * (d - 1)/d
// <= 2^32 * (1 - 1/d) < 2 * (2^31 - 1) = 2^32 - 2.
// The claim follows by applying the ceiling function.
//
// b) For any 0 <= n < 2^31, floor(Mn/2^p) = floor(n/d).
// Proof: Put x = floor(Mn/2^p); it's the unique integer for which
// Mn/2^p - 1 < x <= Mn/2^p. (2)
// Using M >= 2^p/d on the LHS and (1) on the RHS, we get
// n/d - 1 < x <= n/d + n/(2^31 d) < n/d + 1/d.
// Since x is an integer, it's not in the interval (n/d, (n+1)/d),
// and so n/d - 1 < x <= n/d, which implies x = floor(n/d).
//
// c) For any -2^31 <= n < 0, floor(Mn/2^p) + 1 = ceil(n/d).
// Proof: The proof is similar. Equation (2) holds as above. Using
// M > 2^p/d (d isn't a power of 2) on the RHS and (1) on the LHS,
// n/d + n/(2^31 d) - 1 < x < n/d.
// Using n >= -2^31 and summing 1,
// n/d - 1/d < x + 1 < n/d + 1.
// Since x + 1 is an integer, this implies n/d <= x + 1 < n/d + 1.
// In other words, x + 1 = ceil(n/d).
//
// Condition (1) isn't necessary for the existence of M and s with
// the properties above. Hacker's Delight provides a slightly less
// restrictive condition when d >= 196611, at the cost of a 3-page
// proof of correctness.
// Note that, since d*M - 2^p = d - (2^p)%d, (1) can be written as
// 2^(s+1) >= d - (2^p)%d.
// We now compute the least s with this property...
