Maybe these packages could be relevant/useful:

Hello list,
I'm going to implement an interval arithmetic library (following the IEEE P1788) in Haskell and for that I need support for directed rounding to the nearest floating point number. I had a quick look at the Decimal package which comes with the `roundTo` function for rounding to a specified number of decimal places but it doesn't provide directed rounding. Is there way to get directed rounding to to the nearest float (maybe even with machine floats) ?
I'm also aware of the AERN-* packages but they seem to be unmaintained. At least there is no version which builds with the current GHC. Does anybody know something about that ?
Regards
dominik
