About this app

A small calculator application which implements a variety of operations over the space of complex numbers exposed in a very counter-intuitive fashion.

To use the application, input your number into the input field along the top of the screen, and then press the button for the operation which you want.
Complex numbers can be inputted by typing the real part, the sign (plus or minus), then the imaginary part, then an exclamation point or i (the calculator interprets an exclamation point as i). Do not press the i button last, as it fills the number field with "i".
The calculator doesn't currently include the ability to interpret expressions such as "1+2" correctly - only expressions with both real and imaginary parts, in that order, may have a plus or minus sign anywhere but in front.
For operations with two numbers (binary operations) such as addition (a+b), the application will store the value entered and the operation and display a "calculate" button in the top bar. Enter your desired value and then press calculate to perform the operation.

Support for languages besides English and right-to-left layouts is not currently included, but it is planned to release in the near future.

Development proceeds on GitHub: https://github.com/za419/Android-calculator.

While there is currently no pre-release testing build, you can sign up to receive open pre-releases at https://play.google.com/apps/testing/com.Ryan.Calculator.

New features

New in version 2.0: The largest release in the history of this app. Enable the use of complex numbers in almost all operations. Users can enter complex numbers by typing them in as "a+bi". Interpret an exclamation point as i in case it is more convenient(such as on the number pad). Since "Prime?" does not support complex operands (it is not defined over the complex numbers), add a Gaussian Prime function. Finally, improve tablet and TV support, and use an optimizing build to reduce download size
