-- Title : Fixed Point and Floating Point types package
--
-- Library : This package shall be compiled into a library
-- symbolically named IEEE.
--
-- Developers: Accellera VHDL-TC and IEEE P1076 Working Group
--
-- Purpose : Definitions for use in fixed point and floating point
-- arithmetic packages
--
-- 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

package fixed_float_types is
-- Types used for generics of fixed_generic_pkg
type fixed_round_style_type is (fixed_round, fixed_truncate);
type fixed_overflow_style_type is (fixed_saturate, fixed_wrap);
-- Type used for generics of float_generic_pkg
-- These are the same as the C FE_TONEAREST, FE_UPWARD, FE_DOWNWARD,
-- and FE_TOWARDZERO floating point rounding macros.
type round_type is (round_nearest, -- Default, nearest LSB '0'
round_inf, -- Round toward positive infinity
round_neginf, -- Round toward negative infinity
round_zero); -- Round toward zero (truncate)
