Re: [Haskell-cafe] Directed rounding in haskell ?

It might also be worthwhile to have a look at some prior art: http://hackage.haskell.org/package/Ranged-sets On Thu, Apr 10, 2014 at 5:15 PM, Alp Mestanogullari wrote:

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
