fixed_extensions_pkg is a fixed-point arithmetic package written in VHDL
according to the VHDL-2008 update of the standard. It uses VHDL-2008 back-
compatible libraries (by David Bishop) that are included in this distribution
for the sake of completeness.

Currently, the "fixed_extensions_pkg" package implements the following:

round towards plus infinity.
round towards zero.
round towards minus infinity.
round to nearest; ties to greatest absolute value.
round to nearest; ties to plus infinity.
round to nearest; ties to closest even.
bit-field insertion to word

fixed_extensions is distributed along with a tool (gentestround) to generate
customized VHDL test designs.
