■ Exemples.
(10+2+5+7+8)/5
min(4,5,1,6,2)
pi*pow(2,2) (Surface d'un cercle de 2 cm de rayon)
4*pi*pow(2,2) (Surface d'une sphère de 2 cm de rayon)
■ Les fonctions actuelles.
pi, cos, acos, sin, asin, tan, atan, exp, log, max, min, pow, round
L'astuce consiste à utiliser JavaScript pour le retour du résultat. Vous pouvez ajouter facilement d'autres fonctionnalités.Code : Tout sélectionner
