Bonjour à tous,
une petite question pour des spécialistes de l'implémentation des flottants et du GNAT. Nous utilisons le compilateur GNAT sur machine Sun/Solaris et nous nous posons la question suivante :
si un flottant est compris entre deux  nombres représentables en machine comment le compilateur gère l'arrondi, au plus bas au plus haut. Est-ce configurable comme cela est le cas en C et si oui comment par un attribut du langage, une option de compilation ou autre ?

Merci de votre aide
