FAQ:

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

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

* 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 'Radix Modes' is disabled in the settings.

Only one thing missing... ... Engineering suffixes p, n, u, k, etc for Pico, nano, micro, kilo, etc. No calculator for Android has that which is so sad.

Hrishik Mukherjee

Awesome.. Everyone should try!! My Xperia E3 came with a stupid preloaded calculator. So had to install another calculator. I am very happy. Nice work guys

Ashok Moghe

The only scientific calc you need Not only the best calculator around, it's layout is perfect. The end to end screen design and the "Casio" style layout makes me nostalgic and comfortable with the Casio style scientific calculator that I grew up with. Kudos to the development team for bringing up such an outstanding app.

Kashif Khan

Missing date and time operations This calculator still misses calculating addition, subtraction and multiplication of date and time as provided by our windows 7 operating system calculator. Would love to see those features here in this app.

Mike Shea

This app needs a redesign Unless you are entering very simple expressions, it is too hard to tell what you entered. The display screen needs to be larger and parentheses need to actually be displayed around what you want instead of showing an icon on the top right of the screen.

Berk Do

Amazing! I use this when I am not next to my physical calculator! A must have app for any Android phone. 5/5

User reviews

Good apps still exist! I love it. It does a superb job, any calculations you can think of. It is also very compact, which means the developers really took care when writing the code, (which is something most others (read:the big developers) don't really care for lately letting apps get to over 50 megabytes). Congratulations on a job well done.

Best RPN scientific calculator I prefer this app to all of my HP's. Been using them since my first HP 45 in 1976. My only complaint is that I can't pay for an upgrade outside of Google play or PayPal. So I want to send them money but am not willing to give up my credit card info under who knows what is in the EULA.

Outstanding product! I've used this calculator for tasks spanning from physics and high level math to accounting and everyday arithmetic. It has replaced my stock android calc. I use it primarily in RPN mode. I have tried many other 3rd party calcs...none come close to RealCalc's UI and performance. It's the best calc out there! And there are no ads!

Love it more but.. Very quick response to my last review and issue fixed within 3-4 days during the holidays! Haptic feedback control now available on gingerbread phone. New menu button not showing up on my nexus 7 (2012) running KitKat.

Quartic Software December 23, 2014

Hi, this option is still there, go to Menu - Settings - Button Feedback and adjust slider to zero. It is independent of the system setting. If it's not there, please contact the developer (see Menu - About). # What's New

* New 7-segment and dot-matrix displays

* 12-digit display (RealCalc Plus only)

* Increased internal precision (32-digit) (RealCalc Plus only)

* New RPN modes: buffered-entry, XYZT rolling stack (RealCalc Plus only)

A simple calculator, the display of which indicates expressions and gives easy operation for editing.

The calculator PanecalST includes features below:

*Four arithmetic operations, root, percentages, and tax calculations

*Calculations with parentheses

* Memory, M+, M-, MR, MC

*Scroll up/down lines

*Easy editing by using a cursor operation

* Cut, copy, and paste

*Expressions history and answer history

*Configurable grouping separator and decimal point

Four arithmetic operations:

1 + 2 - 3 × 4 ÷ 5 = 0.6

Root:

√( 2 × 2 ) = 2

Percentages:

500 + 20% = 600

500 - 20% = 400

500 × 20% = 100

100 ÷ 500% = 20

Tax calculation:

500 Tax+= 525

525 Tax-= 500

Parentheses:

( 1 + 2 ) × ( 3 + 4 ) = 21

( 1 + 2 ) ( 3 + 4 ) ( 5 + 6 ) = 231

Grouping separator and decimal point:

123,456,789.1 + 0.02 = 123,456,789.12

123.456.789,1 + 0,02 = 123.456.789,12
