The Calculator is a simple pocket calculator.
This saves you the trouble of having to find where it is on your computer if you only have to do basic operations.
It looks like a classic calculator.
By default, it is displayed as a free window, that is to say not anchored to the Ancestris workspace.
You can use the Window Menu to dock or release it.
It can be used with the keyboard or with the mouse like a normal calculator.
Apart from its window, there are no other elements for customizing the Calculator.
