Complex is very simple!

It's an implementation of complex numbers (you know, a + bi), something that Java has been sorely lacking.

All together, it's only three files:

• Complex.java - The Complex type itself. Stores real and imaginary parts as doubles, offers some conversion/equality/output functions, and that's it.
• ComplexMath.java - Some basic mathematical functions, reworked to function with the Complex type. Includes add, subtract, multiply, divide, pow, and so forth.
• ComplexConversionException.java - A RuntimeException subclass designed to shout at you if you try to convert a Complex into a primitive.

Honestly, I don't know.

Just copy Complex's three files (mentioned above) into your project. No libraries or packages are required. Complex's comments also contain JavaDoc tags, so feel free to generate your own documentation.
