In Haskell if I write
[x/10 | x <- [1,3..10]]
I obtain
[0.1, 0.3, 0.5, 0.7, 0.9, 1.1]
What's wrong?

2`[1,3..10]` is wrong. Don't write that. – Reid Barton Jun 25 '16 at 17:53

Why? What fixes that, i.e. to 0.9? – Joan Tarrasso Jun 25 '16 at 17:55

`[1,3..9]` of course. – Reid Barton Jun 25 '16 at 17:56

1But if you want `[0.1, 0.3, 0.5, 0.7, 0.9]` then just write `[0.1, 0.3..0.9]`. Maybe you've oversimplified your real question? – Reid Barton Jun 25 '16 at 18:00

1Yes, but if I do [1,3..10] in ghci it displays [1,3,5,7,9] – Joan Tarrasso Jun 25 '16 at 18:01

If I do that, the last term isn't exactly 0.9. It's 0.899999999999999 – Joan Tarrasso Jun 25 '16 at 18:06

Thank you very much! I'm going to see this link. – Joan Tarrasso Jun 25 '16 at 18:22
