ASINH 3M "Sep 1, 2002" "SunOS 5.11" "Mathematical Library Functions"
NAME
asinh, asinhf, asinhl - inverse hyperbolic sine functions
SYNOPSIS

```cc [ flag... ] file... -lm [ library... ]
#include <math.h>

double asinh(double x);
```

```float asinhf(float x);
```

```long double asinhl(long double x);
```
DESCRIPTION

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

RETURN VALUES

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.

ERRORS

No errors are defined.
