  FLOOR(3M)                (Math Libraries)               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 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, | x|.
