public class Complex

extends Real2

Complex - complex number - derived from Real2

Complex represents a complex number. A reasonable number of arithmetic operations are included - DeMoivre's theorem is used for some of them so there may be quicker implementations elsewhere.

Fields inherited from class jumbo.euclid.Real2

x, y

Constructor Summary

Complex()

Complex(Complex a)

Complex(double a)
