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
