NAME

12       ldiv, lldiv - compute quotient and remainder of a long division
13

SYNOPSIS

15       #include <stdlib.h>
16
17       ldiv_t ldiv(long numer, long denom);
18       lldiv_t lldiv(long long numer, long long denom);

DESCRIPTION

22       These functions shall compute the quotient and remainder of  the  divi‐
23       sion  of  the numerator numer by the denominator denom. If the division
24       is inexact, the resulting quotient is the long integer (for the  ldiv()
25       function)  or  long  long  integer (for the lldiv() function) of lesser
26       magnitude that is the nearest to the algebraic quotient. If the  result
27       cannot   be   represented,   the   behavior  is  undefined;  otherwise,
28       quot * denom+rem shall equal numer.
29

RETURN VALUE

31       The ldiv() function shall return a structure of type ldiv_t, comprising
32       both  the  quotient  and the remainder. The structure shall include the
33       following members, in any order:
34
35
36              long   quot;    /* Quotient */
37              long   rem;     /* Remainder */
38
39       The lldiv() function shall return a structure of type lldiv_t, compris‐
40       ing  both  the  quotient and the remainder. The structure shall include
41       the following members, in any order:
42
43
44              long long   quot;    /* Quotient */
45              long long   rem;     /* Remainder */
