Math Library (libm, -lm)
SYNOPSIS
#include <math.h>
double
asinh(double x);
float
asinhf(float x);
DESCRIPTION
The asinh() and the asinhf() functions compute the inverse hyperbolic
sine of the real argument x. For a discussion of error due to roundoff,
see math(3).
RETURN VALUES
The asinh() and the asinhf() functions return the inverse hyperbolic sine
of x.
