DIV(3)

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 demonstrate 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);

# SEE ALSO

# STANDARDS

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