[Hugs-users] Arithmetical series

[Paqui Lucio]

Hi,
Please, what is the exactly meaning of [n,m..m’]?
or where can I find a precise explanation obout this arithmetical series?

I mean, it seems quite strange that, for example:   

Prelude> [1.2,3.3..8]
[1.2,3.3,5.4,7.5]

Prelude> [1.2,3.3..9]
[1.2,3.3,5.4,7.5,9.6] 

Prelude> [1,-3..(-14)]
[1,-3,-7,-11]      

Prelude> [1,-3..(-15)]
[1,-3,-7,-11,-15]   

Thanks in advance,
Paqui
