2902 * Math.sinh
2904 * mathematically sinh(x) if defined to be (exp(x)-exp(-x))/2
2905 * 1. Replace x by |x| (sinh(-x) = -sinh(x)).
2908 * 0 <= x <= 22 : sinh(x) := --------------, E=expm1(x)
2911 * 22 <= x <= lnovft : sinh(x) := exp(x)/2
2912 * lnovft <= x <= ln2ovft: sinh(x) := exp(x/2)/2 * exp(x/2)
2913 * ln2ovft < x : sinh(x) := x*shuge (overflow)
2916 * sinh(x) is |x| if x is +Infinity, -Infinity, or NaN.
2917 * only sinh(0)=0 is exact for finite x.
2919 double sinh(double x) {
2930 // For |x| < 2^-28, sinh(x) = x
