13 /* sinh(x)
15 * mathematically sinh(x) if defined to be (exp(x)-exp(-x))/2
16 * 1. Replace x by |x| (sinh(-x) = -sinh(x)).
19 * 0 <= x <= 22 : sinh(x) := --------------, E=expm1(x)
22 * 22 <= x <= lnovft : sinh(x) := exp(x)/2
23 * lnovft <= x <= ln2ovft: sinh(x) := exp(x/2)/2 * exp(x/2)
24 * ln2ovft < x : sinh(x) := x*shuge (overflow)
27 * sinh(x) is |x| if x is +INF, -INF, or NaN.
28 * only sinh(0)=0 is exact for finite x.
