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 IEEE Std 1003.1-2001 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 */
