DIV(3)                  NetBSD 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 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.


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);
