NAME
asinh, asinhf, asinhl - inverse hyperbolic sine functions

SYNOPSIS
cc [ flag... ] file... -lm [ library... ]
#include <math.h>

double asinh(double x);

float asinhf(float x);

long double asinhl(long double x);

DESCRIPTION
These functions compute the inverse hyperbolic sine of their argument x.

RETURN VALUES
Upon successful completion, these functions return the inverse hyperbolic sine of their argument.

If x is NaN, NaN is returned.

If x is +-0 or +-Inf, x is returned.

ERRORS
No errors are defined.
