FLOOR(3M) SysV 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:
zero 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|.
