-FUNCTION
-	<<asinh>>, <<asinhf>>---inverse hyperbolic sine 
-
-INDEX
-	asinh
-INDEX
-	asinhf
-
-ANSI_SYNOPSIS
-	#include <math.h>
-	double asinh(double <[x]>);
-	float asinhf(float <[x]>);
-
-TRAD_SYNOPSIS
-	#include <math.h>
-	double asinh(<[x]>)
-	double <[x]>;
-
-	float asinhf(<[x]>)
-	float <[x]>;
-
-DESCRIPTION
-<<asinh>> calculates the inverse hyperbolic sine of <[x]>.
-<<asinh>> is defined as 
-@ifinfo
-. sgn(<[x]>) * log(abs(<[x]>) + sqrt(1+<[x]>*<[x]>))
-@end ifinfo
-@tex
-$$sign(x) \times ln\Bigl(|x| + \sqrt{1+x^2}\Bigr)$$
-@end tex
-
-<<asinhf>> is identical, other than taking and returning floats.
-
-RETURNS
-<<asinh>> and <<asinhf>> return the calculated value.
-
-PORTABILITY
-Neither <<asinh>> nor <<asinhf>> are ANSI C.

-/* asinh(x)
- * Method :
- *	Based on 
- *		asinh(x) = sign(x) * log [ |x| + sqrt(x*x+1) ]
- *	we have
- *	asinh(x) := x  if  1+x*x=1,
- *		 := sign(x)*(log(x)+ln2)) for large |x|, else
- *		 := sign(x)*log(2|x|+1/(|x|+sqrt(x*x+1))) if|x|>2, else
- *		 := sign(x)*log1p(|x| + x^2/(1 + sqrt(1+x^2)))
