Method Detail

getInstance

public static FractionField getInstance()

Get the unique instance.

Returns:

the unique instance

getOne

public Fraction 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<Fraction>

Returns:

multiplicative identity of the field

getZero

public Fraction 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<Fraction>

Returns:

additive identity of the field
