-/* __ieee754_atanh(x)
-   Method :
-      1.Reduced x to positive by atanh(-x) = -atanh(x)
-      2.For x>=0.5
-		    1              2x                          x
-	atanh(x) = --- * log(1 + -------) = 0.5 * log1p(2 * --------)
-		    2             1 - x                      1 - x
-
-	For x<0.5
-	atanh(x) = 0.5*log1p(2x+2x*x/(1-x))
-
-   Special cases:
-	atanh(x) is NaN if |x| > 1 with signal;
-	atanh(NaN) is that NaN with no signal;
-	atanh(+-1) is +-INF with signal.
