quotient and remainder from
division
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <stdlib.h>
div_t
div(
int
num,
int denom);
ldiv_t
ldiv(
long int
num,
long int denom);
lldiv_t
lldiv(
long long
int num,
long long int
denom);
#include <inttypes.h>
imaxdiv_t
imaxdiv(
intmax_t
num,
intmax_t denom);
DESCRIPTION
These functions compute the value of
num / denom and
return the quotient and remainder in a specific divison structure. The
functions differ only with respect to the type of the return value and the
parameters.
The returned structure always contains two members named
quot and
rem, denoting the
quotient and the remainder. The type of these correspond with the underlying
type of the function.
EXAMPLES
The following example demonstrates the basic usage of the functions.
div_t d;
int a = 4321;
int b = 1234;
d = div(a, b);
(void)printf("%d %d\n", d.quot, d.rem);
