    What does the SQL statement look like that you're running? It's a bit hard to tell from
the test itself. I'd stick to something simple like this:
    
        SELECT .1 e 100, .01 e + 100, 1. e -100, 1.23 e 200 FROM SYSTEM.CATALOG LIMIT 1;
    
    And then do the rs.getObject(1), rs.getObject(2), etc.
