sinh()                   Calculate Hyperbolic Sine
 
 #include   <math.h>
 
 double     sinh(x);                     Hyperbolic sine
 double     x;                           Angle, in radians
 
    sinh() return the hyperbolic sine of 'x' radians.
 
    Returns:    Hyperbolic sine of 'x'.  If the result is too large,
                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()
                function.
 
                OVERFLOW first occurs with 'x' greater than 7.0E2
 
  -------------------------------- Example ---------------------------------
 
    The following statements print the hyperbolic sine of pi/2 and 220 pi
    radians, and check for overflow.
 
         #include <math.h>        /* for sinh() and ERANGE */
         #include <stdio.h>       /* for printf() */
         #include <stdlib.h>      /* for errno */
 
         main()
         {
             double hsine, pi = 3.1415926535;
 
             hsine = sinh(pi/2.0);
             printf("hyperbolic sine of pi/2 = %e\n", hsine);
             errno = 0;
             hsine = sinh(220.0 * pi);
             if (errno == ERANGE)
                 printf("ERANGE error in sinh()\n");
             printf("hyperbolic sine of 220 * pi = %e\n", hsine);
         }
