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

⏎ Conversion of units is the conversion between different units of measurement for the same quantity, typically through multiplicative conversion factors. There are many different unit converters available for you, but this one has multiple advantages.
• Eye-appealing graphics
• Well-designed conversion chart
• User-friendly interface
• Moveable to SD card
• Round-based on decimal places
• Commonly used abbreviations for units such as cm for centimeters, km for kilometer, in for inches etc.
• Both Imperial and Metric conversion
Another great feature of this converter is that it is not overwhelmed with thousand different unit categories but it actually contains those most commonly used ones. If you want to convert feet to meters, you can do that quite easily without too much searching for the length converter category. This toolbox has 14 different categories including length, mass (weight converter), volume and area as the most popular ones that you can use to convert Celsius to Fahrenheit or to check how many pounds there are in 33 kilograms.
Other categories here are Speed, Fuel consumption and Time Converter that go hand in hand and are excellent when on road trip. Angle, power, pressure and force converter are put in this app for the more advanced converters, such as physics students or other scientist who got tired of manual calculators. Digital Storage or data and Digital Imaging categories are cool extras.
If you think there is an important unit category missing from this app, please inform us ASAP!
★★★★★Things you didn’t know★★★★★
The system of imperial units or the imperial system is the system of units first defined in the British Weights and Measures Act of 1824, which was later refined and reduced. The system came into official use across the British Empire.
The metric system is an internationally agreed decimal system of measurement that was originally based on the mètre and the kilogramme introduced by France in 1799. Over the years, the definitions of the metre and kilogram have been refined and the metric system has been extended to incorporate many more units. The term is now often used as a synonym for "SI" or the "International System of Units"—the official system of measurement in almost every country in the world.
Over a millions users rely on and trust Unit Converter making it the #1 unit converter for Android.
Unit Converter will never contains Ads and includes a currency converter with over 60 currencies.
New! Now you can unlock the full list of 169 currencies found in Unit Converter Plus for just $0.99 (USD). This gives you full access to the same 169 currencies if you'd rather not purchase the full Unit Converter Plus.
** Tips & Tricks **:
** You can filter the main list of conversions to only show the ones you want by going to Preferences -> Filter Main List.
** By default when you open the currency screen and it's been over a day since the rates have been downloaded, the app will attempt to download the current rates. You can turn this off by going to Preferences -> Auto Update Currency.
** If you want to delete a particular favorite then on the Favorite conversion list Long-Press the one to delete and a pop-up will allow you to delete it.
** If you would like to copy the output of a conversion Long-Press the result box and a pop-up will allow you to copy it to the clipboard. Then you can Long-Press the input value box and select paste.
*** PLUS VERSION INFO ***
* If you are looking for more currencies and more features, please consider Unit Converter Plus. It contains over 100 more currencies, several calculators (tip calculator, PayPal fee calculator, 4 function calculator) and the ability to add custom units.
Ohm's law: Voltage = Current x Resistance
Power law: Power = Voltage x Current
Set any two, and the other two can be calculated.
This application allows you to continually lock one parameter and input another, enabling rapid "what-if" recalculation.
Use the keypad to enter a value then tap on the parameter you want to set. It is now fixed, as shown by the padlock symbol.
Enter another parameter and the remaining two are calculated. The most recently entered parameter becomes the new fixed one.
You can alter which parameter is fixed by tapping it when the input box is empty, or by dragging the padlock to it.
You can "Freeze" a parameter with a long press until it changes color. Now alter any of the other three as required. To unfreeze, with the input box empty, tap any other parameter.
The value of the fixed parameter may not be changed. If you attempt to do so, the padlock will flash. In this case, fix another parameter first.
Supports price quotes in: grams, kilos, ounces, pennyweights and in 23 different currencies.
Also has a calculator, click the widget to use.

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.
