Prototype

double sinh(double x);

long double sinhl(long double x);

Description

Calculates hyperbolic sine.

sinh computes the hyperbolic sine.

sinl is the long double version; it takes a long double argument and returns a long double result. Error handling for sinh and sinhl can be modified through the functions _matherr and _matherrl.

Return Value

sinh and sinhl return the hyperbolic sine of x.

When the correct value overflows, these functions return the value HUGE_VAL (sinh) or _LHUGE_VAL (sinhl) of appropriate sign. Also, the global variable errno is set to ERANGE.

Example

#include <stdio.h>
#include <math.h>
int main(void)
{
   double result, x = 0.5;
   result = sinh(x);
   printf("The hyperbolic sin of %lf is %lf\n", x, result);
   return 0;
}
