FLOOR(3M)       DOMAIN/IX Reference Manual (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 (as a double-precision number) the largest
     integer that is not greater than x.

     Ceil returns the smallest integer that is not less than x.

     Fmod returns the floating-point remainder of the division of
     x by y.  The remainder is zero if y is zero or if x/y would
     overflow.  Otherwise, fmod returns 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, i.e., |x|.
