Synopsis
#include <math.h>
float sinhf(float x);
Description

sinhf calculates the hyperbolic sine of x.

Fast math library behavior

If |x| >~ 88.7228, errno is set to EDOM and sinhf returns HUGE_VALF.

IEC 60559 math library behavior

If x is +∞, -∞, or NaN, sinhf returns |x|.
If |x| >~ 88.7228, sinhf returns +∞ or -∞ depending upon the sign of x.

Portability

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