Exemples

L’exemple suivant compare le reste de la DivRem méthode avec le reste retourné par la Remainder méthode pour établir que les deux méthodes calculent des restes identiques.

Remarques

Le signe du reste est le signe du dividend paramètre.

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

Si nécessaire, la méthode effectue automatiquement la conversion implicite d’autres types intégraux en BigInteger objets avant d’effectuer l’opération de module.
