Method Detail

getInstance

public static BigFractionField getInstance()
Get the unique instance.

Returns:
the unique instance

getOne

public BigFraction 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<BigFraction>
Returns:
multiplicative identity of the field

getZero

public BigFraction 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<BigFraction>
Returns:
additive identity of the field
