ENG mode work wrong
The ENG mode doesn’t seem to work like my physical HP-41cv calculator. The point of engineering notation is to work mostly with whole numbers. This app seems to convert everything to a decimal when an ENG mode. For example, 123 shows up as “0.123 03” rather than “123.000 00” and 16,000,000 shows up as “0.0160 09” rather than “16.0000 06”. Maybe there’s a setting for this, but I can’t find it so this app isn’t useful to me.Show lessDaveKener
Not working
Can’t get this app to do anythingjceaser
Functional issues
Entered 17.3, 0.92 X and got zero. Repeated calculation and sometimes it displays the correct value but if I immediately repeat the calculation, each time thereafter I get a different result and value is decreasing.
Stack problem?
GUI looks good but math functions need to produce the right valuesShow lessRM1796
Leading Zero
I am seeing the same issue. If you multiply 50 by .5 you get zero. If you multiply 50 by 0.5 you get 25. Seems like a new issue. Otherwise I really like this app. Used a 41C since the 80’s. Can’t use anything but RPN.bspurloc

This app no longer works on my phone. I tried deleting it and reinstalling it and it still does not work. Not all the keys are showing. It’s like it’s zoomed in on the upper right side of the calculator.Lisa Avgousti

Unreliable
I’ve been using this app for years and really loved it for the familiarity of RPN and the fact that it works fairly like my HP41CV.
I opened it yesterday to do a simple percentage calculation (40 * .25) and I get zero. It repeatedly returns zero. I guess this is the end of this great free app.Rumblerider
Stuck in scientific notation
Why did the latest upgrade stick my calculator in scientific notation? No idea how to switch back and no instructions provided.Wordie Eddie
Bug
There is a bug with the decimal key. Please fix!!!!HP41forme
Worst mistake a calculator can make
So far, this calculator has given me the wrong answer to every question I have asked it.
60 x .5 = 50?
12% of 100 = 6?
It seems to get it wrong more often than not. A calculator that gets the wrong answers is worse than useless.
As much as I would like a free 41c emulator, this isn’t it.Signals42
