floor(3M) 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.
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|.
returns the absolute value of |x|.
