Poznámky

Znaménko zbytku je znaménko parametru dividend .

Metoda Remainder je implementována pro jazyky, které nepodporují vlastní operátory. Jeho chování je stejné jako dělení pomocí operátoru modulus.

V případě potřeby metoda automaticky provede implicitní převod jiných integrálních typů na BigInteger objekty před provedením operace modulus.
