-/* __ieee754_atanhl(x)
- * Method :
- *    1.Reduced x to positive by atanh(-x) = -atanh(x)
- *    2.For x>=0.5
- *                   1              2x                          x
- *	atanhl(x) = --- * log(1 + -------) = 0.5 * log1p(2 * --------)
- *                   2             1 - x                      1 - x
- *
- *	For x<0.5
- *	atanhl(x) = 0.5*log1pl(2x+2x*x/(1-x))
- *
- * Special cases:
- *	atanhl(x) is NaN if |x| > 1 with signal;
- *	atanhl(NaN) is that NaN with no signal;
- *	atanhl(+-1) is +-INF with signal.
