#include <math.h>
double sinh(double x);
Description

sinh calculates the hyperbolic sine of x.

Fast math library behavior

If |x| >~ 709.782, errno is set to EDOM and sinh returns HUGE_VAL.

IEC 60559 math library behavior

If x is +?, -?, or NaN, sinh returns |x|.
If |x| >~ 709.782, sinh returns +? or -? depending upon the sign of x.

Portability

sinh conforms to ISO/IEC 9899:1990 (C90) and ISO/IEC 9899:1999 (C99).
