- - ### 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

    - #### getRuntimeClass

          public Class<? extends FieldElement<BigFraction>> getRuntimeClass()

      Returns the runtime class of the FieldElement.
      Specified by:
        `getRuntimeClass` in interface `Field<BigFraction>`
      Returns:
        The `Class` object that represents the runtime class of this object.
