PROLOG
       This  manual page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (consult the correspond-
       ing 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
       The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here
       and the ISO C standard is unintentional. This volume of POSIX.1-2008 defers to the ISO C standard.

       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  structure  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 structure shall include
       the following members, in any order:

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