Thank you for fixing the order of x/y for the nth root operation in RPN. That was one of my pet peeves.

Calculator is nice in all aspects but I felt little pain when used it for calculations involving degree minute seconds. DMS facility should be available as primary button so that we can input data faster. Yeah Sam, I can get back to dms from fraction by long pressing dms button, thanks for your help, but still I feel it is not as smooth as entering numerals when we require only dms arithmetic, an exclusive dms mode switch or dms as primary button may fix it for users like me, I think.

The only calc that allows easy scientific notation i.e. 5.1e3 input. Great overall in other aspects.

Finding a free calculator that has 1/x, +/-, and DMS was impossible until now. My only issue is when the result is a negative number, I will select the +/- and a new line starts with a negative instead of turning the result into positive. I have not yet figured out how to start a new line using the result from the previous line as I have only used single line calculators... until now.

EDIT 2024/1/3: Nice calculator. (1) Pressing 1/x should immediately return the value of 1/current answer or 1/current input, without any further input from the user. (2) The +/- button should always change the sign of whatever value is currently displayed, whether that value is the result of a calculation or user input. Pressing +/- should not trigger the start of a new line and a completely new calculation that starts with zero. These issues have not actually been addressed.

Although the new updated, is not as good as the old one, still very good. However, there is a bug there that the old one didn't have that bug. 0^0 = 1 The new version show an error message.
