Agreed, but I was thinking section 5.1's techniques starting on page 104 for large integer addition and subtraction may also be useful for floating point? He found performance benefits using a second kernel for carry propogation, and I wonder if there's an opportunity to do something similar here. Though you may well already be doing something similar.

Yes I think we're the state of the art in what concerns carry propagation :)
