CASIO fx-50F

CASIO fx-50F A simple but cute calculator. At first I wanted to make an emulator of the good old CASIO calculator (fx-50F model), but then, as usual, I wanted to do something my own way and here is a remix of this calculator. There is nothing complicated about it, so I don't write any comments. Just a couple of remarks: I added 10 more memory slots. Right-click to put into memory, left-click to take away, and middle-click to clear.
