Floating preprocessing numbers

In section 3.1.8, a preprocessing number does not acquire a type or a
value until conversion in translation phase 7. I think there is an
omission. A value, and surely a type, must be acquired when an #if
directive is examined during preprocessing.
So the question is, why can't a preprocessing number look like this?
123.45e67
In any other context, e.g. an actual floating constant token in phase 7
which did not derive from a preprocessing number, this is acceptable.
The "e" does not have to be followed by a sign. Why, for #if, must the
"e" be followed by a sign? (And are there any other situations with
the same requirement?)
