PROLOG

6       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
7       implementation of this interface may differ (consult the  corresponding
8       Linux  manual page for details of Linux behavior), or the interface may
9       not be implemented on Linux.

NAME

12       div — compute the quotient and remainder of an integer division
13

SYNOPSIS

15       #include <stdlib.h>
16
17       div_t div(int numer, int denom);
18

DESCRIPTION

20       The functionality described on this reference page is aligned with  the
21       ISO C  standard.  Any  conflict between the requirements described here
22       and the ISO C standard is unintentional. This  volume  of  POSIX.1‐2017
23       defers to the ISO C standard.
24
25       The  div()  function  shall  compute  the quotient and remainder of the
26       division of the numerator numer by the denominator denom.  If the divi‐
27       sion is inexact, the resulting quotient is the integer of lesser magni‐
28       tude that is the nearest to the algebraic quotient. If the result  can‐
29       not   be   represented,   the   behavior   is   undefined;   otherwise,
30       quot*denom+rem shall equal numer.
31

RETURN VALUE

33       The div() function shall return a structure of type  div_t,  comprising
34       both the quotient and the remainder. The structure includes the follow‐
35       ing members, in any order:
36
37
38           int  quot;  /* quotient */
39           int  rem;   /* remainder */
