Sen kayar nokta aritmetik ile dikkatli olmak zorunda. İşte tam 1,1 temsil edemez, bu yüzden

Prelude> [0,0.1 .. 1] 
[0.0,0.1,0.2,0.30000000000000004,0.4,0.5,0.6,0.7,0.7999999999999999,0.8999999999999999,0.9999999999999999] 

iyi yolu daha gibidir denerseniz: Aslında

Prelude> map (/10) [0..10] 
[0.0,0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9,1.0]
