The point of the empty type code is to make sure a number looks like a
float (so as to avoid formatting 2.0 as "2"). But if we have an
exponent, the result already looks like a float, so there's no need to
modify the number further.

Just for the public record, I think that getting rid of the '.0' is the
right thing to do here.
