I am seeing the same issue. If you multiply 50 by .5 you get zero. If you multiply 50 by 0.5 you get 25. Seems like a new issue. Otherwise I really like this app. Used a 41C since the 80’s. Can’t use anything but RPN.
This app no longer works on my phone. I tried deleting it and reinstalling it and it still does not work. Not all the keys are showing. It’s like it’s zoomed in on the upper right side of the calculator.
