Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`T`	`getOne()`	Get the multiplicative identity of the field.
`T`	`getZero()`	Get the additive identity of the field.

- Method Detail
  - getZero
```
T 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.
    
    Returns:
    
    additive identity of the field
  - getOne
```
T 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.
    
    Returns:
    
    multiplicative identity of the field
