32 * mathematically sinh(x) if defined to be (exp(x) - exp(-x)) / 2
33 * 1. Replace x by |x| (sinh(-x) = -sinh(x)).
36 * 0 <= x <= 22 : sinh(x) := -------------, E = expm1(x)
39 * 22 <= x <= lnovft : sinh(x) := exp(x) / 2
40 * lnovft <= x <= ln2ovft: sinh(x) := exp(x / 2) / 2 * exp(x / 2)
41 * ln2ovft < x : sinh(x) := x * shuge (overflow)
44 * sinh(x) is |x| if x is +INF, -INF, or NaN.
45 * only sinh(0) = 0 is exact for finite x.
