sinh Function

Calculates the hyperbolic sine function of a double precision floating-point value.

Include

<math.h>

Prototype

double sinh (double x);

Argument

x

value for which to return the hyperbolic sine

Return Value

Returns the hyperbolic sine of x.

Remarks

A range error will occur if the magnitude of x is too large.

Example

#include <math.h>
#include <stdio.h>
#include <errno.h>

int main(void)
{
  double x, y;

  errno = 0;
  x = -1.5;
  y = sinh (x);
  if (errno)
    perror("Error");
  printf("The hyperbolic sine of %f is %f\n",
          x, y);

  errno = 0;
  x = 0.0;
  y = sinh (x);
  if (errno)
    perror("Error");
  printf("The hyperbolic sine of %f is %f\n",
          x, y);

  errno = 0;
  x = 720.0;
  y = sinh (x);
  if (errno)
    perror("Error");
  printf("The hyperbolic sine of %f is %f\n",
          x, y);
}

Example Output

The hyperbolic sine of -1.500000 is -2.129279
The hyperbolic sine of 0.000000 is 0.000000
Error: range error
The hyperbolic sine of 720.000000 is inf
