public class ComplexDouble

extends java.lang.Object

implements java.lang.Cloneable

This defines a double-precision complex number class. Methods are provided for all standard complex arithmetic operations. Those methods returning ComplexDouble objects are actually returning this one, which allows operations to be cascaded together in one line - e.g.:

   ComplexDouble a, b, c;
   .
   .
   a.mult(b).add(c);    // a = (a*b) + c;
   .
   .
