Name
       asinh, acosh, atanh - inverse hyperbolic functions

Syntax
       #include <math.h>

       double asinh(x)
       double x;

       double acosh(x)
       double x;

       double atanh(x)
       double x;

Description
       The and functions compute the designated inverse hyperbolic functions for real arguments.

   Errors Because of Roundoff, Etc.
       These functions inherit much of their error from the function.

Diagnostics
       The function returns the default quiet NaN if the argument is less than one.

       The function returns the default quiet NaN if the argument has an absolute value greater than or equal to one.

NAME

       asinh, asinhf, asinhl - inverse hyperbolic sine functions

SYNOPSIS

       cc [ flag... ] file... -lm [ library... ]
       #include <math.h>

       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.

ERRORS

       No errors are defined.
