Pardon the questions from the gallery, but ... I can sure see that
0.3 shouldn't be included in the result by overshooting the limit
(i.e., 0.30000000000000004), and the above expectations about
[0,2..9] are obvious enough, but now I have to ask about [0,2..8] -
would you not expect 8 in the result?  Or is it not an upper bound?
