sinh(), sinhf()

hyperbolic sine function 

Function


SYNOPSIS

#include <math.h>

double sinh(double x)

float sinhf(float x)


DESCRIPTION

The sinh() function computes the hyperbolic sine of x.

To check for errors, set errno to 0 before calling sinh(). If errno is non-zero on return, or the return value is NaN, an error has occurred.

The sinhf() function is a single-precision version of sinh().


PARAMETERS

x 

Is the number whose hyperbolic sine is to be computed.


RETURN VALUES

The sinh() function returns the hyperbolic sine value.

If x is NaN, NaN is returned and if in POSIX mode, errno is set to EDOM.

If sinh() underflows, 0.0 is returned.

If the return value would overflow, then:
