The 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 the "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 the original expression works as well.
