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

ПРОЛОГ

       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.

ИМЯ

       div — compute the quotient and remainder of an integer division

СИНТАКСИС

       #include <stdlib.h>

       div_t div(int numer, int denom);

ОПИСАНИЕ

       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.1‐2017 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.

ЗНАЧЕНИЕ, ВОЗВРАЩАЕМОЕ ФУНКЦИЕЙ

       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 */
