- Method Detail
  - getInstance
```
public static ComplexField getInstance()
```
    Get the unique instance.
    
    Returns:
    
    the unique instance
  - getOne
```
public Complex getOne()
```
    Get the multiplicative identity of the field.
    The multiplicative identity is the element e₁ of the field such that for all elements a of the field, the equalities a × e₁ = e₁ × a = a hold.
    
    Specified by:
    
    getOne in interface Field<Complex>
    
    Returns:
    
    multiplicative identity of the field
  - getZero
```
public Complex getZero()
```
    Get the additive identity of the field.
    The additive identity is the element e₀ of the field such that for all elements a of the field, the equalities a + e₀ = e₀ + a = a hold.
    
    Specified by:
    
    getZero in interface Field<Complex>
    
    Returns:
    
    additive identity of the field
