Franco answers a question :
Hello haskellers,is there a reason why Integer doesn't have 'NaN' as
value?I think it would be very convenient to be able to handle (1 `div` 0)
as regular NaN value and not as exception.Thanks.
I think because, if you need NaN like values, `Maybe Int` does the same job
without tainting the definition of `Int`.
This is not a Haskell problem. For Ints, ALL representations are valid
numbers, a NaN is a specific float object, unless I'm mistaken, so the
introduction of such an abnormal number would require some serious
modifications of the representation.
