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