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
19

DESCRIPTION

21       The div() function shall compute the  quotient  and  remainder  of  the
22       division  of the numerator numer by the denominator denom. If the divi‐
23       sion is inexact, the resulting quotient is the integer of lesser magni‐
24       tude  that is the nearest to the algebraic quotient. If the result can‐
25       not be represented, the behavior is undefined; otherwise, quot*  denom+
26       rem shall equal numer.
27

RETURN VALUE

29       The  div()  function shall return a structure of type div_t, comprising
30       both the quotient and the remainder. The structure includes the follow‐
31       ing members, in any order:
32
33
34              int  quot;  /* quotient */
35              int  rem;   /* remainder */
