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.

I'm sorry, but is there a question in there? H. writes:

(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)

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 Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com

7e-3 < 8e-4 The result should be False, but it's True. Basically I don't know where to report this bug.

Sending to the maintainer of the package, as listed on hackage. Antoine

This was my first idea as well, but there's no email: http://hackage.haskell.org/package/numbers
