Vim command
%s/\(\.\d\+\)\@<=0\+\>//g
will strip all trailing (meaningless) zeroes in decimal fractions. Some of my data files lost 50% fat after this procedure and also became much more human readable.
I guess "correct"regular expression should be
\(\.\d\{-1,}}\)\@<=0\+\>
(since the intention is to preserve just one zero that comes right after decimal point), but for some reason original expression works as well.
I guess this serves as another example of how \@<= regexp token makes things so much easier.

| Can't you just use Regexp memory here?

This is a great tip, but there's a little typo. There should only be one closing brace not two. }
Thanks!
