DIV(3P)                    POSIX Programmer's Manual                   DIV(3P)



PROLOG
       This manual page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may dif-
       fer (consult the corresponding Linux manual page for details of Linux behavior), or the interface  may  not  be
       implemented on Linux.

NAME
       div - compute the quotient and remainder of an integer division

SYNOPSIS
       #include <stdlib.h>

       div_t div(int numer, int denom);


DESCRIPTION
       The  div()  function  shall  compute  the  quotient and remainder of the division of the numerator numer by the
       denominator denom. If the division is inexact, the resulting quotient is the integer of lesser  magnitude  that
       is  the nearest to the algebraic quotient. If the result cannot be represented, the behavior is undefined; oth-
       erwise, quot* denom+ rem shall equal numer.

RETURN VALUE
       The div() function shall return a structure of type div_t, comprising both the quotient and the remainder.  The
       structure includes the following members, in any order:


              int  quot;  /* quotient */
              int  rem;   /* remainder */

ERRORS
       No errors are defined.
