------------ RPN-21 Calculator. ------------------- This calculator works a bit differently than the "normal" calculator and takes a bit of getting used to. Example: to add 12 and 18 use the following keystrokes: "12" "Enter" "18" "+" *** ALPHA WARNING *** I just wanted to get the ALPHA out for a proof of concept. There are some display issues which need to be cleaned up ... i.e. buggy code. Also, right now it doesn't do scientific notation, nor all of the functions (including shifted blue functions). I also have to sharpen up the image which I downloaded from http://spyropoulos.net/hp/images/21.jpg Pi is only significant to 9 digits. Have fun scratching!
