On HPPA with float datetimes with today's code, Michael's case works
but it took me less than two minutes to find one that doesn't:

regression=# select interval '14 mon' * 8.2 as product_h;
 9 years 6 mons 23 days 24:00:00
(1 row)

I reiterate my comment that this approach will never work; any small
amount of experimentation will turn up cases that don't round correctly
on one platform or another.  Float arithmetic is inherently inexact.
