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

PROLOG         top

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

NAME         top

       div — compute the quotient and remainder of an integer division

SYNOPSIS         top

       #include <stdlib.h>

       div_t div(int numer, int denom);

DESCRIPTION         top

       The functionality described on this reference page is aligned with
       the ISO C standard. Any conflict between the requirements described
       here and the ISO C standard is unintentional. This volume of
       POSIX.1‐2008 defers to the ISO C standard.

       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; otherwise,
       quot*denom+rem shall equal numer.

RETURN VALUE         top

       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 */
