Re: [Haskell-cafe] instance Enum Double considered not entirelygreat?

Quoth "Richard O'Keefe" , [ ... re " Why would you write an upper bound of 0.3 on a list if you don't expect that to be included in the result? " ]

Because upper bounds are *UPPER BOUNDS* and are NOT as a rule included in the result. If you write [0,2..9] you - DO expect 0 in the result - DON'T expect 9 in the result - would be outraged if 10 were in the result.

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? Donn
