NAME

asinh, asinhf, asinhl — inverse hyperbolic sine functions

SYNOPSIS

Math Library (libm, -lm)
#include <math.h>

double
asinh(double x);

float
asinhf(float x);

long double
asinhl(long double x);

DESCRIPTION

The asinh() function computes the inverse hyperbolic sine of the real argument. The asinhf() function is a single precision version of asinh(). The asinhl() function is an extended precision version of asinh().

RETURN VALUES

The asinh(), asinhf() and asinhl() functions return the inverse hyperbolic sine of x.
