So 1.005.04b03.7 -> 1 . (0.05) . (0.4) b (0.3) . 7 and 02b05 -> (0.2) b (0.5), so that 020.5 < 10.3? > I don't know which scheme is best.

You shouldn't think of `4.6.2' as a "number". Anyway, it's a nifty idea, but I'm not sure if it's worth the effort. Btw, the current scheme is not simple and easy to describe. -Oliver
