3.4. Complex Numbers

KPNCalc will now do arithmetic with complex numbers. Complex numbers are to be be entered like those on an HP48 calculator. The numbers should be entered between parenteses with a comma between the real and imaginary numbers. Ex: 4+5i = (4,5). This would be done by pressing the '()' button, pressing the 4 button, pressing the ',' button, pressing the 5 button, and pressing the '()' button again.

Only simple arithmetic is supported at this time. Trig fuctions, logarithms and other more complex functions will be added as I do the research to find out how to compute them. It has been a while since my calculus days. If any body wish to send me these, please, feel free.
