Class Complex

java.lang.Object
  Complex

public class Complex
extends java.lang.Object

Immutable, complex numbers. A Complex consists of a real and imaginary part, called Cartesian coordinates. The Complex class provides methods for arithmetic such as: add, subtract, multiply, divide, negate and invert. Also provided are complex functions sin, cos, tan, asin, acos, atan, sqrt, log, exp, pow, sinh, cosh, tanh, atanh. Source code Complex.java
