- > Can you compute complex numbers and/or "i" in Pascal...if so, how.
-
- Not too hard. I've done that With some fractal Programs, which were
- written For TP5 (it might be easier using OOP With the later versions).
-
- I use two Variables For a complex number of a+bi, usually expressed as
- xa and xb (or x.a and x.b as a Record).
-
- For addition/subtraction (complex z=x+y):
-
- z.a:=x.a+y.a;
- z.b:=x.b+y.b;
-
- For multiplication:
-
- z.a:=(x.a*y.a)-(x.b*y.b);
- z.b:=(x.a*y.b)+(x.b*y.a);
- }
