--  This package contains the implementation for Ada.Wide_Text_IO.Decimal_IO.
--  Routines in this package are identical semantically to those in Decimal_IO,
--  except that the default parameters have been removed because they are
--  supplied explicitly by the calls from within these units, and there is an
--  additional Scale parameter giving the value of Num'Scale. In addition the
--  Get routines return the value rather than store it in an Out parameter.
