This is the sixth realase of KPNCalc. KPNCalc is a polish notation calculator. It was inspired by hours of HP48G calculator use. I have tried to include as many useful features as came to mind. The GUI is not the cleanest, but I am not an UI expert. I am open to suggestions for both new functions and a new layout.
For those of you not familiar with Polish notation caluclators. The numbers should be added to the stack before the operation is performed. The calculator used double precision, and the stack is only limited by your computers memory.
KPNCalc will do simple arithmetic operations with complex numbers and allows user to write their own operations in python
0.4 - added complex numbers
0.5 - ported to KDE2
0.6 - Added user operations and xml GUI
