     Name
          floor, fabs, ceil, fmod - Performs absolute value, floor,
          ceiling and remainder functions.

     Syntax
          #include <math.h>

          double floor (x)
          double x;

          double ceil (x)
          double x;

          double fmod (x, y)
          double x, y;

          double fabs (x)
          double x;

     Description
          fabs returns |x|.

          floor returns the largest integer (as a double precision
          number) not greater than x.

          ceil returns the smallest integer not less than x.

          fmod returns the number f such that x = iy + f, for some
          integer i, and 0 _ f<y.
