Warren- No, a 100% error would be 40 GHz. Where did you get 40.4 GHz? That 
would be 101% and of course 80 GHz is 200%.

Bruce- Of course you are right about the + symbol for 40.000 000 003 GHz 
(+7.5 parts in 1E-11) but what would you consider current standard notation. 
We still Use this metric notation in the US. What do you use?
