The best Calc forever

I wish it can be access from the widgets or simply replace the original one.

Pas mal mais des fonctions manquantes

Du type historique déroulant par exemple.

pratique et bien pensée

Les grosses touches multi-fonctions sont pratiques et les fonctions mémoires et variables sont bien pensées.
Cool!

Great

По-настоящему быстрый

Для быстрых вычислений самая оптимальная альтернатива. Если что не стечняйтесь в хэелп глянуть, там тоже всё адекватно — просто и наглядно.
