SYNOPSIS

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);

DESCRIPTION

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

RETURN VALUE

37       The div_t (etc.) structure.
38

CONFORMING TO

40       SVr4,  4.3BSD,  C89.  The functions lldiv() and imaxdiv() were added in
41       C99.
42

EXAMPLE

44       After
45
46               div_t q = div(-5, 3);
47
48       the values q.quot and q.rem are -1 and -2, respectively.
