Remarques

Les méthodes Multiply permettent d’effectuer des opérations de multiplication qui impliquent des nombres complexes.

Si la multiplication entraîne un dépassement de capacité dans le composant réel ou imaginaire, la valeur de ce composant est Double.PositiveInfinity ou Double.NegativeInfinity.

La méthode Multiply est implémentée pour les langages qui ne prennent pas en charge les opérateurs personnalisés. Son comportement est identique à la multiplication à l’aide de l’opérateur de multiplication.
