- - ### Method Detail

    - #### getInstance

          public static final Decimal64Field getInstance()

      Returns the unique instance of this class.
      Returns:
        the unique instance of this class

    - #### getZero

          public Decimal64 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<Decimal64>`
      Returns:
        additive identity of the field

    - #### getOne

          public Decimal64 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<Decimal64>`
      Returns:
        multiplicative identity of the field

    - #### getRuntimeClass

          public Class<? extends FieldElement<Decimal64>> getRuntimeClass()

      Returns the runtime class of the FieldElement.
      Specified by:
        `getRuntimeClass` in interface `Field<Decimal64>`
      Returns:
        The `Class` object that represents the runtime class of this object.
