DIV(3) | Library Functions Manual | DIV(3)

# NAME

`div`, `ldiv`, `lldiv`, `imaxdiv` —
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);

# STANDARDS

All described functions conform to ISO/IEC 9899:1999 (“ISO C99”).
