--  This package contains the routines for Ada.Wide_Text_IO.Float_IO that
--  are shared among separate instantiations of this package. The routines
--  in this package are identical semantically to those in Float_IO, except
--  that the default parameters have been removed because they are supplied
--  explicitly by the calls from within the generic template. This package
--  is also used by Ada.Wide_Text_IO.Fixed_IO and Ada.Wide_Text_IO.Decimal_IO.
