Well, he referred to 12.3.2, which says “Round to nearest” means round the result of a floating-point operation to the representable value nearest the result. If the two nearest representable values are equally near the result, the one having zero as its least significant bit shall be delivered. That should be pretty clear, and referring to text elsewhere in the standard is a good idea. -- Bernd Paysan "If you want it done right, you have to do it yourself" net2o ID: kQusJzA;7*?t=uy@X}1GWr!+0qqp_Cn176t4(dQ* http://bernd-paysan.de/
