-FUNCTION
-<<acosh>>, <<acoshf>>---inverse hyperbolic cosine
-
-INDEX
-acosh
-INDEX
-acoshf
-
-ANSI_SYNOPSIS
-        #include <math.h>
-        double acosh(double <[x]>);
-        float acoshf(float <[x]>);
-
-TRAD_SYNOPSIS
-        #include <math.h>
-        double acosh(<[x]>)
-        double <[x]>;
-
-        float acoshf(<[x]>)
-        float <[x]>;
-
-DESCRIPTION
-<<acosh>> calculates the inverse hyperbolic cosine of <[x]>.
-<<acosh>> is defined as
-@ifinfo
-. log(<[x]> + sqrt(<[x]>*<[x]>-1))
-@end ifinfo
-@tex
-$$ln\Bigl(x + \sqrt{x^2-1}\Bigr)$$
-@end tex
-
-<[x]> must be a number greater than or equal to 1.
-
-<<acoshf>> is identical, other than taking and returning floats.
-
-RETURNS
-<<acosh>> and <<acoshf>> return the calculated value.  If <[x]>
-less than 1, the return value is NaN and <<errno>> is set to <<EDOM>>.
-
-You can change the error-handling behavior with the non-ANSI
-<<matherr>> function.
-
-PORTABILITY
-Neither <<acosh>> nor <<acoshf>> are ANSI C.  They are not recommended
-for portable programs.

-/* acosh(x)
- * Method :
- *	Based on 
- *		acosh(x) = log [ x + sqrt(x*x-1) ]
- *	we have
- *		acosh(x) := log(x)+ln2,	if x is large; else
- *		acosh(x) := log(2x-1/(sqrt(x*x-1)+x)) if x>2; else
- *		acosh(x) := log1p(t+sqrt(2.0*t+t*t)); where t=x-1.
- *
- * Special cases:
- *	acosh(x) is NaN with signal if x<1.
- *	acosh(NaN) is NaN without signal.
