Listen Read Device Only Added Installed NHN-1 is a free advanced engineering and scientific calculator with a transparent widget that has fractions and percentage:

•A resizeable widget with arithmetic, percentage button, and fractions.

•Expression (formula) based input.

•Fraction input and output with conversion to proper fraction, mixed fraction and decimal. Even the quadratic or cubic root functions, for instance, will return fractions when the answer can be written as a fraction.

•Full history with buttons that load old results, in case you need to start over from a previous point.

•Unlimited memory slots that can be named and are always displayed on screen.

•Multiple input fields except on small phones. This let's you do short side calculations without losing your place.

•Pre-packaged functions for quadratic equations as well as many geometric formulae.

•Buttons that store user defined functions that are created by binding an argument to a binary operator.

•Visualization of multivalued complex functions (roots, inverse trigonometric, logarithm)

•Visualization of quadratic and cubic functions

•Visualization of angles returned from inverse trigonometric functions.

•Complex numbers are very easy to work with, and all functions work with complex numbers where they are defined (inverse hyperbolic cosine, for instance).

•There is a fourth layout for small phones that is not shown in the screen shots.

•A unit conversion utility that lets you build arbitrary composite units. Conversion factors are written to the history, so you can bind the factor with multiplication to do the same conversion many times.

The layouts are designed to be ergonomic for each of four device sizes in portrait and landscape. Here are some examples of what we've done to make the calculator easy and speedy to work with:

•On small tablets in landscape, the keys are split so you can operate the calculator with two thumbs.

•On small phones, the numeric keypad is right under your thumb when holding the device with one hand.

•Square root, square, inverse and negation are all close to the numeric keypad.

•On small tablets, the long "NHN-1" button is a gesture recognizer that lets you scroll the six input fields with your left thumb. That way you don't have to let go of the device with your right hand to click an input field.

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

++ 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
