Bonjour leraystep
leraystep95 a écrit:Bonjour, J'aimerais utiliser la fonction arrondit dans mon calcul. Mais dès que j’intègre (, -1) pour avoir un arrondit à la dizaine près.
round(abs(device(3175494))+(device(3175698)), -1)
J'ai le message "too many arguments (2 given, 1 expected)" et l'ERREUR: Valeur lue vide
Alors qu'avec : round(abs(device(3175494))+(device(3175698))) le résultat est correct ! Comment je peux faire ?
C'est parce que le script original ne sait pas traiter les fonctions à 2 paramètres (pow,round) d'où la réponse - Code : Tout sélectionner
"too many arguments (2 given, 1 expected)"
J'ai fait des versions corrigées qui permettent d'utiliser les fonctions à 2 variables, d'autres fonctions et même des fonctions temporelles les versions vont de 1.0 à 1.8 et 2.0. Il y a longtemps que je n'ai pas repris les évolutions, il semble que la 1.3 soit stable : elle tourne sans problème chez moi opérateurs fonctionnant

on peut aussi définir des fonctions "utilisateur"
Il y a une version 2.0 de la doc qui pourrait aider, mais qui n'est pas complètement correcte car la version 2.0 (n'est pas stable, je n'ai pas eu le temps de la terminer) mais qui serait valable pour un bon nombre de fonctions.
code stable (probablement la 1.3)
