> As discussed on the mailing-list, it is proposed to develop a wrapper class around the
{{double}} primitive type. This wrapper class should implement {{FieldElement}}. This would
allow generic calculations on exchangeable number types (big fractions, big decimals, fractions,
decimals). This class will be called {{Decimal64}} (together with the corresponding {{Decimal64Field}}).

> Similarly, to the {{BigReal}} class, the newly created {{Decimal64}} class could go to
the {{o.a.c.m3.util}} package.
