LDIV(3P)                                            POSIX Programmer's Manual                                           LDIV(3P)



PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (con-
       sult the corresponding Linux manual page for details of Linux behavior), or the  interface  may  not  be  implemented  on
       Linux.

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

SYNOPSIS
       #include <stdlib.h>

       ldiv_t ldiv(long numer, long denom);
       lldiv_t lldiv(long long numer, long long denom);


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

RETURN VALUE
       The ldiv() function shall return a structure of type ldiv_t, comprising both the quotient and the remainder.  The  struc-
       ture shall include the following members, in any order:


              long   quot;    /* Quotient */
              long   rem;     /* Remainder */

       The lldiv() function shall return a structure of type lldiv_t, comprising both the quotient and the remainder. The struc-
       ture shall include the following members, in any order:


              long long   quot;    /* Quotient */
              long long   rem;     /* Remainder */
