Great calculator. Feature request: Please add some basic finance options like margin-markup etc
Does all the stuff i want in a quick scientific calc except graphing and full expression input, which i like not having because the app can more easily be shown split screen.
Feature request: would be great if we could divide by zero and find the real square-root of -1. Also, doesn't calculate pi to a terminating digit, which is disappointing.
Fully featured, intuitive calculator.
Great
It's a very nice calculator app. I like rpn but I'm not a huge fan of the hp calc emulators, this one is all the math and none of the gimmick.
Best calculator, period. Calculator is well laid out and works perfectly for me. RPN spectacular! Free one is good, but I bought this to support the developer.
Plus paid version worth every penny...
My 'real' calculator is a HP41C and this is the only workable substitute that I've found for when I'm not at the office. This tells you all about the quality of this particular piece of software.
