ldiv(3p)
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 */
