 ceil()                  Calculate Ceiling of Value

 #include <math.h>

 double     ceil(x);                     Ceiling of value
 double     x;                           Floating point value

    ceil() returns a double value of the smallest integer that is greater
    than or equal to 'x'.

       Returns:     Smallest integer >= 'x'. There is no error return.

   -------------------------------- Example ---------------------------------

    The following statements calculate the ceiling of 3.3, 0.0 and -3.3.

           #include <math.h>      /* Required for function definition only */

           main()
           {
               double x, y, z;

               x = ceil(3.3);     /* x = 4.0 */
               y = ceil(0.0);     /* y = 0.0 */
               z = ceil(-3.3);    /* z = -3.0 */
           }
