[Haskell-cafe] Newbie question: alternative for toInt/fromInt

[peterv]

That would be too easy ;) Coming from C++, that was the first I tried too.
But in Haskell, an Win32.INT is not an Int:

GraphicsTypes.hs:46:16:
    Couldn't match expected type `Dimension'
           against inferred type `Win32.INT'
    In the expression: id
    In the definition of `toDimension': toDimension = id

GraphicsTypes.hs:47:16:
    Couldn't match expected type `Win32.INT'
           against inferred type `Dimension'
    In the expression: id
    In the definition of `fromDimension': fromDimension = id

Stefan O'Rear "fromIntegral" magic worked fine, thanks!

toInt = id
fromInt = id
