Mathematical Library Functions                          asinh(3M)



NAME
     asinh, asinhf, asinhl - inverse hyperbolic sine functions

SYNOPSIS
     cc [ flag... ] file... -lm [ library... ]
     #include 

     double asinh(double x);


     float asinhf(float x);


     long double asinhl(long double x);


DESCRIPTION
     These functions compute the inverse hyperbolic sine of their
     argument x.

RETURN VALUES
     Upon  successful  completion,  these  functions  return  the
     inverse hyperbolic sine of their argument.


     If x is NaN, NaN is returned.


     If x is ]0 or ]Inf, x is returned.

ERORS
     No errors are defined.
