If you find RealCalc useful, please consider purchasing RealCalc Plus to support further development. Thank you.

FAQ:

* If you want data size conversions in multiples of 1024, use kibibytes, mebibytes, gibibytes, etc - see en.wikipedia.org/wiki/Kibibyte.

* If the percent key appears to give wrong answers, make sure you are pressing '=' at the end, e.g. '25 + 10 % =' will give 27.5.

* If sin/cos/tan functions don't give the answer you are expecting, make sure you are in the correct angle mode. Degrees, radians and grads are supported, indicated by DEG, RAD, GRAD in the display. Use the DRG key to change mode.

* If any of the digit keys are disabled, or the decimal point doesn't work, or you have answers with letters in, or basic arithmetic appears to be wrong, then you are in binary, octal or hexadecimal mode. Press DEC to return to decimal operation. If you don't need these modes, please make sure that 'Enable Radix Modes' is disabled in the settings.

* If you can't find HEX, BIN or OCT modes, go to the settings and make sure that 'Enable Radix Modes' is checked.

Please read the help for more information.

Hey Tony! You should learn how to use the calculator. The early calc you have to put the number first and then "Sine" !! Blame yourself first before others!

Excellent Ad free gully functional Calculator Wonderful free calc. Converts my Galaxy note into a handy Sci Calculator. The conversion tool is also handy though not all that easy to use. Thank you developers......

David Herman

Best calc I've tried And I've tried a lot of them. This one has the most calculator like feel to all of them. I was a little sad that fractions were only on the paid version, as they are very common and something a lot of people use, but it was well worth the upgrade to support

Ðëvånḡ Ṥinḡḫ

Brilliant The best scientific calc in the market, you can store or call answers in memory, find all the physical constants, open up answers history as well as conversion in hexa deci and octa binary too is possible although negative and fractional number cant be converted, just one suggestion, while typing in numbers, it should be visible on screen along with other part as an equation, and solve whole equation straightaway using 'bodmas' application, also add solution for imaginary numbers ad in a 100ms calculator

Jeff Carter

Used to be my fave... I've really liked this calculator app since I've started using it over a year ago. But, recently I needed to solve a problem with a rather large factorial. Even though the solution to the equation was a mere decimal hundredth, the factorial term itself could not be calculated. In fact, I discovered that I could only do factorials to 69! before resulting in an overflow error, while the factorial I was trying to calculate was 365!. Until now, I've always relied on this app. But I only need one, so a sad farewell to this one.

Great Calculator For anything short of WolframAlpha level problems, this calculator is the go to on Android. I particularly love the RPN mode, its perfect.

User reviews

Alright Helpful but the delete button is placed in a weird spot and it has a ugly color the market should have a pretty FREE and HELPFUL pink and blue calculator other than that it's fine

Great Calculator but... It's one of the best scientific calculator apps but now, every time you enter the app it presents the About screen... I know it's a free app, but I don't need to be presented with an about page every time I need to use this app... too bad they go this path... going to move to another calculator...

Great - Especially if you use hp rpn Very nice. First thing I download for a new android device. Has all the standard functions of a scientific calculator. Optional RPN makes it perfect for those of us used to using an hp.

puzzled ??%% either your calculations are wrong or my book(ncert) answers..being a ncert book it can't provide us with wrong answer so conclusion is.....yes your calculations are wrong...it's a good app for science students who can go without accuracy..fix it developers..specially inverse trigonometry functions.

Great app I removed the stock calc and replaced it with this :) @Jonathan, 10/02/12: Before claiming a calc does math wrong, please learn basic math. 28.5 * 2 = 57, not 58. 58.5 / 2 = 29.25, not 28.5 or 28.75. RealCalc gives the correct answer, not your incorrect one, nor the (wrong) one you said RealCalc provided. Trust the calc, Jonathan. It's right and you are wrong.

Best in class With its clean and familiar design, there's no question that this is by far the best replacement calculator available. It also has all the basic functions one could need. An essential app.

Powerful and intuitive Best calculator app I've used on any platform. Has RPN support and both the scientific and programmer modes have all the functions I need with good button layouts that make them easy to find and fast to use. I don't need the Pro features, but am upgrading anyway to say "thanks" and support the developer.

Best seen so far Free version is definately best seen so far. The comments regarding available upgrades in the paid version seem to offer some excellent additions that would be worth paying for. I look forward to using the free version, and will definately consider upgrading as soon as ine or more of the variables are needed. Don't mind paying for "quality", & from what i've seen so far-this app seems very appropriate in this regard. Will come back with an update to this review as that is needed.

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

Listen Read Device Only Added Installed ## Calculator (CyanogenMod)

Xlythe

Listen Read Device Only Added Installed Calculator is focused on extending the traditional 4 function calculator, keeping its simplicity while still adding features used in higher level math. It uses the original Android calculator as a base.

The project was started by me in June 2012 and by October 2012 it was accepted into CyanogenMod. Since then, users of the app have helped greatly in cleaning up the ui, improving the matrix features, and translating the app into all the languages currently available. Without them, this app would be nowhere near as polished as it's become.

Because the app is intended as a full replacement, it's recommended that you hide your default calculator by either disabling it (v4.1+) or using a custom launcher. Otherwise, the similar app names may prove confusing.

Calculator has the following features and more:

-Basic arithmetic

-Trigonometry

-Complex numbers

-Graphs for X,Y functions

-Matrices

-Hexadecimal and Binary support

-Widget for lockscreen and launcher

-Floating calculator

-History of previous calculations

-Themeing support

-Google Glass support

The app is completely open source and the source can be downloaded at: https://github.com/Xlythe/android_packages_apps_Calculator/tree/ics

FAQ:

* If you want data size conversions in multiples of 1024, use kibibytes, mebibytes, gibibytes, etc - see en.wikipedia.org/wiki/Kibibyte.

* If the percent key appears to give wrong answers, make sure you are pressing '=' at the end, e.g. '25 + 10 % =' will give 27.5.

* If sin/cos/tan functions don't give the answer you are expecting, make sure you are in the correct angle mode. Degrees, radians and grads are supported, indicated by DEG, RAD, GRAD in the display. Use the DRG key to change mode.

* If any of the digit keys are disabled, or the decimal point doesn't work, or you have answers with letters in, or basic arithmetic appears to be wrong, then you are in binary, octal or hexadecimal mode. Press DEC to return to decimal operation. If you don't need these modes, please make sure that 'Enable Radix Modes' is disabled in the settings.

* If you can't find HEX, BIN or OCT modes, go to the settings and make sure that 'Enable Radix Modes' is checked.
