Poznámky

Metody Multiply umožňují provádět operace násobení, které zahrnují složitá čísla.

Pokud násobení vede k přetečení v reálné nebo imaginární komponentě, hodnota této komponenty je buď Double.PositiveInfinity, nebo Double.NegativeInfinity.

Metoda Multiply je implementována pro jazyky, které nepodporují vlastní operátory. Jeho chování je stejné jako násobení pomocí operátoru násobení.
