ASINH(3M) Mathematical Library Functions ASINH(3M)

asinh, asinhf, asinhl - inverse hyperbolic sine functions

cc [ flag... ] file... -lm [ library... ]
#include <math.h>
double asinh(double x);

float asinhf(float x);

long double asinhl(long double x);

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

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.

No errors are defined.
