## Simple complex numbers calculator (SimpleCplxCalculator).

Description: Very simple calculator application, that may be used to perform basic arithmetic operations
(add, subtract, multiply, divide) with complex numbers.

To enter a complex number a = x+yi, proceed as follows:

- Enter its real part x, just as you would enter any real number.
- Start entering the imaginary part by pushing the "+i" or "-i" button (depending on the imaginary part's sign).
- Enter the imaginary part y (as you would do for a positive real number).

"Memory" and "Clear" buttons work exactly the same way as they do on a standard calculator.

Possible extensions: Make the application a "real" calculator by adding functions, complex format conversion...

Note: The application uses the "UComplex" unit, downloaded from
GitHub.

Free Pascal features: Basic controls: Menus, push buttons, edit fields. Using the UComplex unit to work with
complex numbers.
