34 * atanh(x)
39 * atanh(x) = --- * log(1 + -------) = 0.5 * log1p(2 * --------)
41 * Note: to guarantee atanh(-x) = -atanh(x), we use
43 * atanh(x) = ------- * log1p(2*-------).
47 * atanh(x) is NaN if |x| > 1 with signal;
48 * atanh(NaN) is that NaN with no signal;
49 * atanh(+-1) is +-INF with signal.
