    • 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
