--- "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
