- * Method :
- *	Based on
- *		acoshl(x) = logl [ x + sqrtl(x*x-1) ]
- *	we have
- *		acoshl(x) := logl(x)+ln2,	if x is large; else
- *		acoshl(x) := logl(2x-1/(sqrtl(x*x-1)+x)) if x>2; else
- *		acoshl(x) := log1pl(t+sqrtl(2.0*t+t*t)); where t=x-1.
- *
- * Special cases:
- *	acoshl(x) is NaN with signal if x<1.
- *	acoshl(NaN) is NaN without signal.
