ldiv, lldiv - compute quotient and remainder of a long division
Návod, kniha: POSIX Programmer's Manual
#include <stdlib.h>
ldiv_t ldiv(long
numer, long
denom );
lldiv_t lldiv(long long
numer, long long
denom );
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.
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 */
