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 */
