++ complex number computations
+ support for a huge variety of functions
++ expression simplification: use 'identical to' sign (≡) to simplify current expression (2/3+5/9≡11/9, √(8)≡2√(2))
+ support for Android 1.6 and higher
+ open source
NOTE ABOUT INTERNET ACCESS: Calculator++ (version 1.2.24) contains advertisement which requires internet access. To get rid of it - purchase a version without ads (can be done from application's preferences).
How can I get rid of the ads?
You can do it by purchasing the special option in the main application preferences.
Why Calculator++ needs INTERNET permission?
Currently application needs such permission only for one purpose - to show ads. If you buy the special option C++ will never use your internet connection.
How can I use functions written in the top right and bottom right corners of the button?
Push the button and slide lightly up or down. Depending on value showed on the button action will occur.
How can I toggle between radians and degrees?
To toggle between different angle units you can either change appropriate option in application settings or use the toggle switch located on the 6 button (current value is lighted with yellow color).
Also you can use deg() and rad() functions and ° operator to convert degrees to radians and vice versa.
268° = 4.67748
30.21° = 0.52726
rad(30, 21, 0) = 0.52726
deg(4.67748) = 268
Does C++ support %?
Yes, % function can be found in the top right corner of / button.
100 + 50% = 150
100 * 50% = 50
100 + 100 * 50% * 50% = 125
100 + (100 * 50% * (25 + 25)% + 100%) = 150
100 + (20 + 20)% = 140, but 100+ (20% + 20%) = 124.0
100 + 50% ^ 2 = 2600, but 100 + 50 ^ 2% = 101.08
Does C++ support fractional calculations?
Yes, you can type your fractional expression in the editor and use ≡ (in the top right corner of = button). Also you can use ≡ to simplify expression.
2/3 + 5/9 ≡ 11/9
2/9 + 3/123 ≡ 91/369
(6-t) ^ 3 ≡ 216 - 108t + 18t ^ 2 - t ^ 3
Does C++ support complex calculations?
Yes, just enter complex expression (using i or √(-1) as imaginary number). ONLY IN RAD MODE!
(2i + 1) ^ = -3 + 4i
e ^ i = 0.5403 + 0.84147i
Can C++ plot graph of the function?
Yes, type expression which contains 1 undefined variable (e.g. cos(t)) and click on the result. In the context menu choose 'Plot graph'.
Does C++ support matrix calculations?
No, it doesn't

Here is where I poke fun at your stupid comments:
This is a working demo of an application I am writing that I'm happy to get feedback about. It currently is able to copy files from a CIFS/Windows share and put them onto your SD card wirelessly.
Display your PVOutput intraday details right in DashClock. This app requires Android 4.2 and DashClock.
In the small widget size it will show your current days accumulated energy generation in watt hours.
In the large widget size it shows your current days accumulated energy generation in watt hours, your most recent power level in watts and your systems overall current efficiency (in current kW per kW installed).
For this extension to operate you must set your PVOutput API key and System ID correctly in the settings for this extension after you add it to your DashClock configuration. The extension will only display data that is less than 4 hours old, if you batch your uploads then it will only display data for 4 hours after the most recent entry in the batch upload. This extension mostly makes sense for PVOutput users who upload their data in near real time.
