```
public class ComplexNumber
extends java.lang.Object
```
Objects of this class model complex numbers. Before creation, the object data could be in polar, rectangular(cartesian) or exponential form, but once created, all states revert to cartesian.

public ComplexNumber(double real,
                     double imag,
                     ComplexState state)
```
    The 2 double arguments have interpretations that vary with the state argument. If state = POLAR , then the first double argument represents the radius or absolute value of the ComplexNumber and the second double argument represents its angle. If state = CARTESIAN , then the first double argument represents the real part of the complex number and the second one represents its imaginary part. If state = EXPONENTIAL, then the first argument represents the radius or absolute value of the ComplexNumber and the second double argument represents its angle just as in the Polar form.
    
    Parameters:
    
    real - The real part in CARTESIAN and the radius in POLAR.
    
    imag - The imaginary part in CARTESIAN and the angle in POLAR
    
    state - The state of the ComplexNumber object, POLAR or CARTESIAN.
