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(), asinhf(), asinhl(): _BSD_SOURCE || _SVID_SOURCE || _XOPEN_SOURCE >= 500 || _ISOC99_SOURCE; or cc -std=c99

DESCRIPTION

The asinh() function calculates the inverse hyperbolic sine of x; that is the value whose hyperbolic sine is x.
