asinh, asinhf, asinhl – inverse hyperbolic sine functions
LIBRARY
Math Library (libm, -lm)

#include <math.h>
double
asinh(double x);
float
asinhf(float x);
long double
asinhl(long double x);
DESCRIPTION
The asinh(), asinhf(), and asinhl() functions compute the inverse hyperbolic sine of the real argument x. For a discussion of error due to roundoff, see math(3).
