Remarques

Les méthodes Add permettent d’effectuer des opérations d’ajout qui impliquent des nombres complexes.

Si l’appel de méthode entraîne un dépassement de capacité dans le composant réel ou imaginaire, la valeur du composant est Double.PositiveInfinity ou Double.NegativeInfinity.

Les langages qui ne prennent pas en charge les opérateurs personnalisés peuvent utiliser la méthode Add pour effectuer des ajouts avec des nombres complexes.

Les méthodes Add qui reçoivent un double sont plus efficaces que les méthodes qui reçoivent deux nombres complexes.
