sinh


function
<cmath>
     double sinh (      double x );
      float sinh (       float x );
long double sinh ( long double x );

Compute hyperbolic sine

Returns the hyperbolic sine of x.

In C++, this function is overloaded in <complex> and <valarray> (see complex sinh and valarray sinh).

Parameters

x
Floating point value.


Return Value

Hyperbolic sine of x.
If the the magnitude of the result is so large that it cannot be represented in an object of the return type, the function returns HUGE_VAL with the same sign as the correct value of the operation, and the value of the global variable errno is set to the ERANGE value.

Portability

In C, only the double version of this function exists with this name.

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

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


Output:

The hyperbolic sine of 0.693147 is 0.750000.
