SYNOPSIS

#include <math.h>

double asinh(double x)

float asinhf(float x)

---

DESCRIPTION

The asinh() and asinhf() functions compute the inverse hyperbolic sine of the real argument.

The asinhf() function is a single-precision version of asinh().

---

PARAMETERS

x 

Value whose inverse hyperbolic sine to compute.

---

RETURN VALUES

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

If x is NaN, NaN is returned. Additionally, in POSIX mode, the global variable errno is set to EDOM, and in SVID and XOPEN modes, the matherr() function is called.
