-- "fixed_float_types" package contains types used in the fixed and floating
-- point packages..
-- Please see the documentation for the floating point package.
-- This package should be compiled into "ieee_proposed" and used as follows:
--
-- This verison is designed to work with the VHDL-93 compilers. Please
-- note the "%%%" comments. These are where we diverge from the
-- VHDL-200X LRM.

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)
