I used to have PowerCalc but it seems is no longer available.
I would like it to be fully scientific and to show parentheses.
If you go to the Google Play store (https://play.google.com/store/
) and then search variously for:
* scientific calculator
* graphing calculator
* tape calculator
- then I suspect that you may find an abundance of good calculators to meet your requirements and you could literally be spoiled for choice.
People naturally tend to have their preferences and that is illustrated by some of the responses given by DCers above - the calculators suggested are all good calculators - but such preferences can sometimes stand in the way of one's finding an even "better" calculator (for one's peculiar requirements), thus, with any apps/proggies I would always recommend taking as wide a view as possible and using an objective "suck-it-and-see" approach. That way, you can risk being surprised to find that what you thought
were your requirements becomes augmented by newly-discovered requirements because of some nifty feature(s) which you hadn't previously realised was/were available or possible - e.g., which was my experience and that of others upon trialling Microsoft OneNote
- "Wait, it can do that?
Wait, that is also possible? Could you elaborate on how to do it? I just did a quick search online, but it seems it is only possible for audio and video recorded by OneNote?
Again, for example, until I stumbled upon it and trialled it, I didn't realise how very useful the Free42 calculator
could be (Free42 is a re-implementation of the HP-42S calculator and the HP-82240 printer).
I know your OP was about an Android-based calculator, but wondered whether you had considered other devices (e.g., the PC). For example, Microsoft Mathematics 4.0 - Mini-Review (scientific math + graphing calculator)
Hope that helps or is of use.
