H A Ds_tanh.c24 * 0. tanh(x) is defined to be -----------
27 * 1. reduce x to non-negative by tanh(-x) = -tanh(x).
28 * 2. 0 <= x <= 2**-55 : tanh(x) := x*(one+x)
30 * 2**-55 < x <= 1 : tanh(x) := -----; t = expm1(-2x)
33 * 1 <= x <= 22.0 : tanh(x) := 1- ----- ; t=expm1(2x)
35 * 22.0 < x <= INF : tanh(x) := 1.
38 * tanh(NaN) is NaN;
39 * only tanh(0)=0 is exact for finite argument.
