[Haskell-beginners] question about round function

[Prashant Shah]

Hi,

This is my first time with Haskell.

Here is what I found while trying out some examples :

Prelude> round 3.499999999999999
3
it :: Integer

Prelude> round 3.4999999999999999
4
it :: Integer

---------------

Prelude> round 111111.49999999999
111111
it :: Integer
Prelude> round 111111.499999999999
111112
it :: Integer

Is it something to do with the CPU register size ?
