John, 

would it be also possible for you to describe roughly 
how to implement,e.g:
   addition, subtraction with rounding at particular 
   decimal position (this is the operation, we have 
   most frequently, followed by comparison)
on SSE, when SSE contains BID ?  This is what we hoped, 
we can learn from you and your people.  We so far could
not figure out how to achieve both the performance and 
the correctness, without restricting the data range.

Thanks,
Nobu
