NAME

       div, ldiv, lldiv - compute the quotient and remainder

SYNOPSIS

       #include <stdlib.h>

       div_t div(int numer, int denom);

       ldiv_t ldiv(long int numer, long int denom);

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

DESCRIPTION

       The div() function computes the quotient and remainder of the division of the numerator numer by the denominator denom. It provides a well-
       defined semantics for the signed integral division and remainder operations, unlike the implementation-defined semantics  of  the  built-in
       operations.    The  sign  of the resulting quotient is that of the algebraic quotient, and if the division is inexact, the magnitude of the
       resulting quotient is the largest integer less than the magnitude of the algebraic quotient. If the  result  cannot  be	 represented,  the
       behavior is undefined; otherwise, quotient * denom + remainder will equal numer.

       The  ldiv()  and lldiv() functions are similar to div(), except that the arguments and the members of the returned structure are different.
       The ldiv() function returns a structure of type ldiv_t and has type long int.  The lldiv() function returns a structure of type lldiv_t and
       has type long long.

RETURN VALUES

       The div() function returns a structure of type div_t, comprising both the quotient and remainder:

	 int   quot;   /*quotient*/
	 int   rem;    /*remainder*/

       The  ldiv()  function returns a structure of type ldiv_t and lldiv() returns a structure of type lldiv_t, comprising both the  quotient and
       remainder:

	 long int   quot;   /*quotient*/
	 long int   rem;    /*remainder*/

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

       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 */
