Inverse hyperbolic sine functions

Part of asinh(3).

Usage

#include <math.h>

double

asinh(double x);

float

asinhf(float x);

long double

asinhl(long double x);

Library

Overview

The asinh(), asinhf(), and asinhl() functions compute the inverse hyperbolic sine of the real argument x. For a discussion of error due to roundoff, see math(3).

Return values

These functions return the inverse hyperbolic sine of x.
