PROLOG

6       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
7       implementation of this interface may differ (consult the  corresponding
8       Linux  manual page for details of Linux behavior), or the interface may
9       not be implemented on Linux.

NAME

13       ldiv, lldiv — compute quotient and remainder of a long division
14

SYNOPSIS

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

DESCRIPTION

22       The functionality described on this reference page is aligned with  the
23       ISO C  standard.  Any  conflict between the requirements described here
24       and the ISO C standard is unintentional. This  volume  of  POSIX.1‐2008
25       defers to the ISO C standard.
26
27       These  functions  shall compute the quotient and remainder of the divi‐
28       sion of the numerator numer by the denominator denom.  If the  division
29       is  inexact, the resulting quotient is the long integer (for the ldiv()
30       function) or long long integer (for the  lldiv()  function)  of  lesser
31       magnitude  that is the nearest to the algebraic quotient. If the result
32       cannot  be  represented,  the   behavior   is   undefined;   otherwise,
33       quot * denom+rem shall equal numer.
34

RETURN VALUE

36       The ldiv() function shall return a structure of type ldiv_t, comprising
37       both the quotient and the remainder. The structure  shall  include  the
38       following members, in any order:
39
40           long   quot;    /* Quotient */
41           long   rem;     /* Remainder */
42
43       The lldiv() function shall return a structure of type lldiv_t, compris‐
44       ing both the quotient and the remainder. The  structure  shall  include
45       the following members, in any order:
46
47           long long   quot;    /* Quotient */
48           long long   rem;     /* Remainder */
