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|.
