     double sinh (double x);      float sinh (float x);long double sinh (long double x);

Compute hyperbolic sine

Returns the hyperbolic sine of x.

Header

<tgmath.h>

provides a type-generic macro version of this function.

Parameters

x: Value representing a hyperbolic angle.

Return Value Hyperbolic sine of x.
If the magnitude of the result is too large to be represented by a value of the return type, the function returns HUGE_VAL (or HUGE_VALF or HUGE_VALL) with the proper sign, and an overflow range error occurs:

If an overflow

range error

occurs, the global variable

errno

is set to

ERANGE

Example

/* sinh example */
#include <stdio.h>      /* printf */
#include <math.h>       /* sinh, log */

int main ()
{
  double param, result;
  param = log(2.0);
  result = sinh (param);
  printf ("The hyperbolic sine of %f is %f.\n", param, result );
  return 0;
}

Output:

The hyperbolic sine of 0.693147 is 0.750000.
