LDIV(P)                                                                LDIV(P)



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 quo-
       tient.  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 */
