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

[CX] 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) orlong 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 */

CHANGE HISTORY

First released in Issue 4. Derived from the ISO C standard.
