  • Method Details

    • 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 java.lang.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.
