Calc-50

There was a minimal description for this app, but I was eager to try it out. Some surprises: 1) Holy hell, this is RPN. Jeez. 2) It’s impossible to copy the answer string. This seriously limits this tool’s usefulness. I’m forced to transcribe the answer into/onto something else. Ideally this should be a copyable field. To the developer... ::: If you’ve already invested the effort to provide fifty digits of precision, I’m guessing that you have robust ‘arbitrary precision’ internals. Please open up the possibility for much higher precision output. Long meaningful/coherent digit strings are useful, even though they may seem like overkill to many people. I am very happy that you’ve created this app. Nobody else has done this so cleanly. So, I thank you for that. Thank you!

This calculator is far more advanced than I expected for such a low price. It has deep and highly technical capabilities, as well as graphing, 50-digit display and lots of rich functions. Also, the help button is quite useful for quick explanation of each function. Highly recommended!
