- Constructor Detail
  - Complex
```
public Complex(double r,
               double i)
```
    Explicit constructor.
    
    Parameters:
    
    r - Real.
    
    i - Imaginary.
- Method Detail
  - getReal
```
public double getReal()
```
    Real part
    
    Returns:
    
    the real
  - getImaginary
```
public double getImaginary()
```
    Imaginary part
    
    Returns:
    
    the imaginary
  - add
```
public Complex add(Complex a)
```
    Add operation.
    
    Parameters:
    
    a - A complex number.
    
    Returns:
    
    The sum of both.
  - multiply
```
public Complex multiply(double x)
```
    Multiplies a complex by a scalar.
    
    Parameters:
    
    x - A number.
    
    Returns:
    
    this*x.
  - exponential
```
public Complex exponential()
```
    Returns the exponential function of certain Complex.
    
    Returns:
    
    Exp(this) as a new Complex.
  - toString
```
public java.lang.String toString()
```
    Converts a Complex into a String of the form ( a + bi).
    This enables the Complex to be easily printed. For example, if z was 2 - 5i, then
    System.out.println("z = " + z);
    would print
    z = (2 - 5i)
    Overrides:
    
    toString in class java.lang.Object
    
    Returns:
    
    String containing the cartesian coordinate representation
