Really impressive. Some calculations are not 100% accurate (some diferences in last decimal places. Probably due to some rounding of the signals in the suboperations). But overall Im amazed this stuff is even possible in LBP. If you compare it with the calculator from LBP1 it is obvious the editor went long way forward in the possibilities.
I was expecting a calculator capable of only doing basic operations. Wow! You completely exceeded my expectations! Excellent job! :)
