ASINH(3)

NAME
asinh, asinhf, asinhl - inverse hyperbolic sine functions

SYNOPSIS
libm
#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.
