There are very many bit patterns that count as NaNs, but only two classes worth distinguishing: qNaNs and sNaNs. The payload bits have no cross-platform significance; if it comes to that, there are two opposing conventions for which value of the is-it-quiet bit, so it's not clear if any distinction is worth making. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
