FLOOR(3M)            INTERACTIVE UNIX System            FLOOR(3M)



          NAME
               floor, ceil, fmod, fabs - floor, ceiling, remainder, abso-
               lute 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|.
