The current format for encoding floating point numbers does not allow for 
compression in the way the format for integer numbers does.  I understand 
this, since the IEEE formats do not offer a means to compress their numbers.

There is another floating point format called unum 
(  This format allows 
for compression and more precisely represents the final number, for a given 

I bring this up as a suggestion to get even more compression into the 
protobuffer format.
