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.
