NAME
div
--- compute the quotient and remainder of an integer division
SYNOPSIS
#include <stdlib.h>
div_t div(int numer, int denom);
DESCRIPTION
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.
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.
The following sections are informative.
EXAMPLES
None.
APPLICATION USAGE
None.
RATIONALE
None.
FUTURE DIRECTIONS
None.
