I am trying to return the length of a list as an Integer type, but applying length xs returns the length as an Int type. How can I work around this issue?
This is what I am trying to achieve: (it does not work)
sizeList :: [Integer] -> Integer
sizeList xs = length xs
It works as soon as I change the return to sizeList :: [Integer] -> Int but I don't want to do so.
You can either call genericLength from Data.List, or call length and use fromIntegral to convert the result.
