RotoValue:

Perhaps you can replace the sprintf function with a wrapped version. I've never replaced the core functions before, but I've seen references to it. Googling for perl replace core function came up with a couple useful looking links:

So perhaps you could do something like:

BEGIN{
    *CORE::GLOBAL::old_sprintf = *CORE::GLOBAL::sprintf;
    *CORE::GLOBAL::sprintf = sub { 
          my $formatted_string = old_sprintf(@_);

          # 0.###Z ==> .###
          $formatted_string =~ s/([^0-9])0(\.\d+)Z/$1$2/g;

          return old_sprintf(@_);
    }
};

Which I adapted (probably incorrectly) from Corion's stack overflow post (the second link). I've never tried to override the core functions, but something like this might be a good solution for you. Of course, you may need to write some magic code to recognize the new format string, and figure out how to do the replacement(s) without messing up other replacements.

If you could do something cheesy like use a format like "blah blah %.fZ blah", and could rely on Z never being at the end of a number in your code, then you could do a replacement like the one I did above.

Update: Added "something like".
