|
-- :
|
|
-- Library : This package shall be compiled into a library
|
|
-- : symbolically named IEEE.

|
|
-- 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
|
|
