Hello,
With ghc-6.10.4 the following results are produced with numbers 2009.8.9: (7e-3 :: BigFloat Prec50) < (6e-4 :: BigFloat Prec50) False (7e-3 :: BigFloat Prec50) < (8e-4 :: BigFloat Prec50) True where in the sourecode is written: data BigFloat e = BF (Fixed e) Integer deriving (Eq, Ord) and import Data.Ratio newtype Fixed e = F Rational deriving (Eq, Ord, Enum, Real, RealFrac) H. _______________________________________________ Haskell-Cafe mailing list [hidden email] http://www.haskell.org/mailman/listinfo/haskell-cafe |
I'm sorry, but is there a question in there?

Basically I don't know where to report this bug. _______________________________________________ Haskell-Cafe mailing list [hidden email] http://www.haskell.org/mailman/listinfo/haskell-cafe |

Oh, wait; that returns False which is correct, but 0.007 < 0.0008 returns True which is incorrect. Which just goes to show I shouldn't skim emails that early in the morning... -- Ivan Lazar Miljenovic [hidden email] IvanMiljenovic.wordpress.com _______________________________________________ Haskell-Cafe mailing list [hidden email] http://www.haskell.org/mailman/listinfo/haskell-cafe |
