But what about that NaN->Integer conversion thing?
I think that may be a bug or at least a misfeature. The standard is somewhat vauge on a lot of issues dealing with floating point since it is such a tricky subject and depends a lot on the environment. The various rounding funcitons are particularly ugly IMHO. I added varients of them that preserved the floating point type and properly implemented IEEE behavior for jhc.
I think the Data.Binary guys think it's a feature, since they rely in this behavior (well, they rely on the equivalently-foolish behavior of toRational). I think it's a bug. David
