5/5
Awesome app
The default Android calculator will fall short for those who need to make complex calculations. RealCalc Scientific Calculator help you out in this way by allowing you to perform formulas and functions (sin,cos,tan...). Thus, you will be able to calculate percentages, binary, octal and hexadecimal terms, functions in degrees radians or grands among many others. What's more, it displays in scientific, engineering and fixed-point modes, as well as RPN mode. It allows you to keep even 10 memories. Especially useful is the data size conversions in multiples of 1024 (Kb, Mb, Gb...).
This is the free version of RealCalc Scientific Calculator. If you like it you can donate £1.99 to the developer by getting the paid version.
RealCalc Scientific Calculator has been developed by Quartic Software, who has just launched the free and paid version of this calculator. It's considered one of the best scientific calculator on the market though.
If you're one of those who daily needs to make some complex calculations, there's no need to buy a scientific calculator: you can download it from here. It's as the same as having a real one but taking advantage of your phone potential. A must have on this issue.
Developer's original description available hereAndroid's #1 Scientific Calculator. A fully featured scientific calculator which looks and operates like the real thing.

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.
Please read the help for more information.
