RealCalc Plus


RealCalc Plus is the enhanced version of Android's #1 Scientific Calculator, RealCalc - a fully featured scientific calculator which looks and operates like the real thing.

RealCalc Plus includes the following features:
* Traditional algebraic or RPN operation
* Fraction calculations and conversion to/from decimal
* Degrees/minutes/seconds calculations and conversion
* 12-digit display
* Extended internal precision (32-digit)
* User-customizable unit conversions
* User-customizable constants
* Percentages
* Result history
* 10 memories
* Binary, octal, and hexadecimal (can be enabled in Settings)
* Trig functions in degrees, radians or grads
* Scientific, engineering and fixed-point display modes
* 7-segment, dot-matrix or standard font display
* Landscape mode
* Configurable digit grouping and decimal point
* Three RPN styles: direct-entry (classic RealCalc mode), buffered-entry, or XYZT rolling stack
- see Menu > Help > RPN Mode for details of the different modes
* Full built-in help

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 enabled.

* 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.

Please read the help for more information.

Recent changes:
* New menu button (above SHIFT) for phones running Honeycomb or later
* New 7-segment and dot-matrix displays
* 12-digit display
* Increased exponent range (999)
* Increased internal precision (32-digit)
* New RPN modes: buffered-entry, XYZT rolling stack
* New repeat-calculation behaviour: press operator twice (K shown in display)
* Constants updated to NIST 2010 values

v2.0.3:
* Restored vibration feedback setting for old devices
* Option to swap left/right keypads in landscape

Unbelievable app, fantastic I use this calculator every day for all kinds of calculations and unit conversions. I've been using it for years, and still find new features. Every time I think of a feature I want it to have, I look around in it and find it. I had upgraded just to support the effort of the developer. However, then I found additional features in the upgraded version that were very useful as well.

Wonderful Calculator! For those who like to use calculators on your phone, this is the best. You can select different default calculator s abd can customize them many different ways. I searched for the best and found it here. You will never need another one.

Still the Best, but... The UI. The dev should implement Material Design principles and an optional flat UI style while retaining ALL the existing functionality and layout. Aside from that, it can't be beat. The new menu button is great.
