I guess I'm disagreeing with the idea of dropping the trailing zero. It should
be retained, since 2 significant figures was what was asked for.
Then it wouldn't be behaving as documented: "Numeric vectors are
encoded with the minimum number of decimal places needed to display all
the elements to at least the |digit| significant digits. However, if all
the elements then have trailing zeroes, the number of decimal places is
reduced until at least one element has a non-zero final digit; see also
the argument documentation for |big.*|, |small.*| etc, above. "
