Behavior near zero ------------------
Relative comparison is problematic if either value is zero. In this case, the difference is relative to zero, and thus will always be smaller than the prescribed tolerance.
I'm not sure I follow the specifics but this is saying that everything will be close to zero. Isn't that the wrong way round? I thought the comments in the discussion on the list were saying that the problem with relative tolerance is that *nothing* is close to zero? Paul
