### 1/5 — Application à revoir

*2020-03-23, version 2.1*

L application ne marche pas.
Des pubs apparaissent au moment d’avoir le résultat presqu’à chaque fois.
De plus il est impossible d écrire des nombres décimaux après exponentielle.
A revoir.... surtout qu’aucune autre application ne produit ce service alors que la demande est grande.
