Structure

Packages

• app: contains calculation related classes

• main: contains the FXML for the layout, the Controller class and the Main class to start the application

• res: contains the resource file for internalisation. As the application is not translated into other languages, this only serves to separate descriptions from layout, so that they are not hardcoded.

• style: contains the CSS file to style the layout

Negative numbers are understood by the calculator:
