A really neat, useful app. it also has polar form which is handy

A Google User

GIVES WRONG ANSWERS!! Gives incorrect answers when the input is in polar form.

A Google User

Great app! Can tell you're an engineer ;)

A Google User

Garbage. Operations in polar form give wrong answers

A Google User

Needs input to be in degrees also, was so confusing at first

A Google User

Wrong answers, try adding in polars.

Listen Read Device Only Added Installed Calculator++ is an advanced, modern and easy to use scientific calculator #1.

Calculator++ helps you to do basic and advanced calculations on your mobile device.

Calculator++ helps you to do basic and advanced calculations on your mobile device.

Discuss Calculator++ on Facebook: http://facebook.com/calculatorpp

IMPORTANT:

1. Always check angle units and numeral bases: trigonometric functions, integration and complex number computation work only for RAD!!!

2. Application contains ads! If you want to remove them purchase special option from application settings. Internet access permission is needed only for showing the ads. ADS ARE ONLY SHOWN ON THE SECONDARY SCREENS! If internet is off - there are no ads!

Features:

++ easy to use

++ home screen widget

+ no need to press equals button any more - the result is calculated automatically

+ smart cursor positioning

+ copy/paste in one button

+ landscape/portrait orientations

++ drag buttons up or down to use special functions, operators etc

++ modern interface with possibility to choose themes

+ highlighting of expressions

+ history with all previous calculations and undo/redo buttons

++ variables and constants support (build-in and user defined)

++ 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).

FAQ

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.

Examples:

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.

Examples:

100 + 50% = 150

100 * 50% = 50

100 + 100 * 50% * 50% = 125

100 + (100 * 50% * (25 + 25)% + 100%) = 150

Note:

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.

Examples:

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!

Examples:

(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
