NAME
asinh() - inverse hyperbolic sine function
SYNOPSIS
#include <math.h>
double asinh(double x);
DESCRIPTION
The asinh() function computes the inverse hyperbolic sine of its argument.
The ISO/ANSI C committee has approved the asinh() function for inclusion in the C9X draft standard.
To use this function, compile either with the default -Ae option or with the -Aa and -D_HPUX_SOURCE
options. Make sure your program includes <math.h>. Link in the math library by specifying -lm on the
compiler or linker command line.
RETURN VALUE
If x is ±INFINITY, asinh() returns ±INFINITY respectively.
If x is NaN, asinh() returns NaN.
ERRORS
No errors are defined.
