-- Title : Floating-point package (Instantiated package declaration)
-- :
-- Library : This package shall be compiled into a library
-- : symbolically named IEEE.
-- :
-- Developers: Accellera VHDL-TC and IEEE P1076 Working Group
-- :
-- Purpose : This packages defines basic binary floating point
-- : arithmetic functions
-- :
-- Note : This package may be modified to include additional data
-- : required by tools, but it must in no way change the
-- : external interfaces or simulation behavior of the
-- : description. It is permissible to add comments and/or
-- : attributes to the package declarations, but not to change
-- : or delete any original lines of the package declaration.
-- : The package body may be changed only in accordance with
-- : the terms of Clause 16 of this standard.
