NAME

6       div,  ldiv, lldiv, imaxdiv - compute quotient and remainder of an inte‐
7       ger division

SYNOPSIS

10       #include <stdlib.h>
11
12       div_t div(int numerator, int denominator);
13       ldiv_t ldiv(long numerator, long denominator);
14       lldiv_t lldiv(long long numerator, long long denominator);
15
16       #include <inttypes.h>
17
18       imaxdiv_t imaxdiv(intmax_t numerator, intmax_t denominator);

DESCRIPTION

26       The div() function computes the value numerator/denominator and returns
27       the quotient and remainder in a structure named div_t that contains two
28       integer members (in unspecified order) named quot and  rem.   The  quo‐
29       tient  is  rounded  toward  zero.   The result satisfies quot*denomina‐
30       tor+rem = numerator.
31
32       The ldiv(), lldiv(), and imaxdiv() functions do the same, dividing num‐
33       bers  of  the indicated type and returning the result in a structure of
34       the indicated name, in all cases with fields quot and rem of  the  same
35       type as the function arguments.
36

RETURN VALUE

38       The div_t (etc.) structure.

CONFORMING TO

50       POSIX.1-2001, POSIX.1-2008, C89, C99, SVr4, 4.3BSD.  The functions  ll‐
51       div() and imaxdiv() were added in C99.

EXAMPLES

54       After
55
56           div_t q = div(-5, 3);
57
58       the values q.quot and q.rem are -1 and -2, respectively.
