Hello,
I have a question. In the class about variables, on the image, there is the float variable missing. I know that double is preferred these days since float can only hold a limited amount of data with precision. However, there are some libraries, that require float, particularly when it comes to graphs.

Wouldn’t it make sense, to include float in the list of variables, even though it is just to have a complete list?

Cheers,

Ben
