33 * tanhl(x) returns the hyperbolic tangent of x
36 * 1. reduce x to non-negative: tanhl(-x) = - tanhl(x).
38 * 0 < x <= small : tanhl(x) := x
40 * small < x <= 1 : tanhl(x) := --------------
43 * 1 <= x <= threshold : tanhl(x) := 1 - ---------------
45 * threshold < x <= INF : tanhl(x) := 1.
56 * tanhl(NaN) is NaN;
57 * only tanhl(0.0)=0.0 is exact for finite argument.
