-------------------------------------------- -- Announcing: logfloat 0.9.1 -------------------------------------------- New official release of the logfloat package for manipulating log-domain floating numbers. This release is mainly for those who are playing with Transfinite rather than LogFloat, but the interface changes warrant a minor version change. If you're just using the LogFloat stuff you shouldn't notice any changes except that the constructors/destructors may be a bit pickier about being used when a polymorphic return type is expected. -------------------------------------------- -- Changes -------------------------------------------- * John Meacham pointed out that the Num and Ord superclasses on Transfinite may be onerous due to the growing disaffection with the Prelude. The Num requirement has been lifted, and the Ord requirement has been weakened to the new PartialOrd class. * Introduced a new class for partially ordered types: PartialOrd. * The transfinite-value respecting logarithm has been moved from Data.Number.LogFloat to Data.Number.Transfinite because it's more appropriate there. (It's still reexported by Data.Number.LogFloat.) * In the continuing battle between transfinite values and Rationals, I've added a new class RealToFrac for overloading the Prelude's realToFrac function. On GHC, primitive converters are used to improve both performance and correctness. For non-GHC compilers, only a few generic instances are given. For an older discussion on this topic, see: http://www.haskell.org/pipermail/haskell-prime/2006-February/000791.html * Due to all this development on trying to solve the issues of transfinite values, the "stability" of the package has been changed from stable to provisional. -------------------------------------------- -- Future Extensions -------------------------------------------- * A strict version. The current lazy version will move to Data.Number.LogFloat.Lazy, and the strict version will be the standard one in Data.Number.LogFloat * A signed version in Data.Number.LogFloat.Signed * A test suite -------------------------------------------- -- Links -------------------------------------------- Homepage: http://code.haskell.org/~wren/ Hackage: http://hackage.haskell.org/cgi-bin/hackage-scripts/package/logfloat Darcs: http://code.haskell.org/~wren/logfloat Haddock (Darcs version): http://code.haskell.org/~wren/logfloat/dist/doc/html/logfloat/ -- Live well, ~wren
