Obviously my next comments relate more to application requirements than the raw input - but even if I had a facility for storing the incoming data in its incoming form (which you do in Oracle with the RAW type), I would probably look at splitting the stream into three tables -

    Values within the specified range
    Special values known to be messages
    Values deemed to be garbage

But I can appreciate why you think it is vital to store numbers as IEEE format.
