NAME

asinh, asinhf, asinhl - inverse hyperbolic sine function  

SYNOPSIS

#include <math.h>double asinh(double x);
float asinhf(float x);
long double asinhl(long double x);

Link with -lm.

Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

asinh():

_ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L
    || _XOPEN_SOURCE >= 500
    || /* Since glibc 2.19: */ _DEFAULT_SOURCE
    || /* Glibc versions <= 2.19: */ _BSD_SOURCE || _SVID_SOURCE

asinhf(), asinhl():

_ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L
    || /* Since glibc 2.19: */ _DEFAULT_SOURCE
    || /* Glibc versions <= 2.19: */ _BSD_SOURCE || _SVID_SOURCE
 

DESCRIPTION

These functions calculate the inverse hyperbolic sine of x; that is the value whose hyperbolic sine is x.  

RETURN VALUE

On success, these functions return the inverse hyperbolic sine of x.

If xis a NaN, a NaN is returned.

If xis +0 (-0), +0 (-0) is returned.

If xis positive infinity (negative infinity), positive infinity (negative infinity) is returned.  

ERRORS

No errors occur.
