floor(3M)                                               floor(3M)



     NAME
          floor,  ceil,  fmod,  fabs  -  floor,  ceiling,   remainder,
          absolute value functions

     SYNOPSIS
          #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
          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 floating-point remainder of the division of
          x by y:  x if y is zero or if x/y would overflow; otherwise
          the number is f with the same sign as x, such that x = iy +
          f for some integer i, and |f| < |y|.

          fabs returns the absolute value of |x|.
