Fonctions de programmation et de types de données

Fonctions pour les opérations bit à bit, les opérateurs et outils sur les types de données et le contrôle des programmes

Effectuez une manipulation bit à bit des objets fi, manipulez le type de données des objets fi et développez des algorithmes à l'aide de fonctions qui supportent les types de données à virgule fixe.
