I still have an action item to discuss "101010.100" as
a potential fixed point format with John Ries (owner of
FT09). I also have an action item for floating point
formats.

If you accept proposal 4, is there any reason I should
pursue the above? Under proposal 4, this format is
not usable in expressions and would only be used in
assignments and initializations. Hence the "." would
only be for user readability and not for determining
bounds.

Cheers,
Jim
