DIV
Linux Programmer's Manual (3)
20130705
NAME
div, ldiv, lldiv, imaxdiv  compute quotient and remainder of
an integer division
SYNOPSIS
#include <stdlib.h>
div_t div(int numerator, int denominator);
ldiv_t ldiv(long numerator, long denominator);
lldiv_t lldiv(long long numerator, long long denominator);
#include <inttypes.h>
imaxdiv_t imaxdiv(intmax_t numerator, intmax_t denominator);
Feature Test Macro Requirements for glibc (see
feature_test_macros(7)):
lldiv():

_XOPEN_SOURCE >= 600  _ISOC99_SOURCE 
_POSIX_C_SOURCE >= 200112L;
or
cc std=c99
DESCRIPTION
The
div()
function computes the value
numerator/
denominator and
returns the quotient and remainder in a structure
named
div_t that contains
two integer members (in unspecified order) named
quot and
rem.
The quotient is rounded toward zero.
The result satisfies
quot*
denominator+
rem =
numerator.
The
ldiv(),
lldiv(),
and
imaxdiv()
functions do the same,
dividing numbers of the indicated type and
returning the result in a structure
of the indicated name, in all cases with fields quot and rem
of the same type as the function arguments.
RETURN VALUE
The
div_t (etc.) structure.
ATTRIBUTES
Multithreading (see pthreads(7))
The
div(),
ldiv(),
lldiv(),
and
imaxdiv()
functions are threadsafe.
CONFORMING TO
SVr4, 4.3BSD, C89. C99.
The functions
lldiv()
and
imaxdiv()
were added in C99.
EXAMPLE
After
div_t q = div(5, 3);
the values
q.quot and
q.rem are 1 and 2, respectively.
