NAME

asinh, asinhf, asinhl —

inverse hyperbolic sine functions

LIBRARY

Math Library (libm, -lm)

SYNOPSIS

#include <math.h>

double
asinh(double x);

float
asinhf(float x);

long double
asinhl(long double x);

DESCRIPTION

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.

HISTORY

The asinh(), asinhf(), and asinhl() functions appeared in 4.3BSD, FreeBSD 2.0, and FreeBSD 10.0, respectively.
