div, ldiv,
lldiv, imaxdiv —
quotient and remainder from division
Standard C Library (libc, -lc)
#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);
These functions compute the value of num / denom and return the quotient and remainder in a specific division 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.
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);
All described functions conform to ISO/IEC 9899:1999 (“ISO C99”).
