hypot()                  Calculate the Hypotenuse of a Right Triangle
 
 #include   <math.h>
 
 double     hypot(x,y);
 double     x,y:                         Floating-point values
 
    hypot() returns the length of the hypotenuse of the right triangle
    with sides of length 'x' and 'y'.  This is the equivalent of:
 
                      sqrt('x' * 'x' + 'y' * 'y');
 
    Returns:    The length of the hypotenuse.  On overflow, matherr() is
                called with an overflow error, 'errno' (defined in
                <stdlib.h>) is set to ERANGE (defined in <math.h>), and
                the value 'HUGE' (defined in <math.h>) is returned.
 
      Notes:    Error handling can be modified by using the matherr()
                routine.
 
  -------------------------------- Example ---------------------------------
 
    The following statements calculate the length of the hypotenuse of a
    right triangle with two sides of length 7.0 and 24.0:
 
         #include <math.h>     /* for hypot() */
 
         main()
         {
             double h;
 
             h = hypot(7.0, 24.0);    /* h = 25.0 */
         }
