FLOOR(3M)                DOMAIN/IX SYS5                 FLOOR(3M)



NAME
     floor, ceil, fmod, fabs - floor, ceiling, remainder, abso-
     lute value functions

USAGE
     #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: zero if y is zero or if x/y would overflow; other-
     wise 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|.
