equip GHC with an accurate internal model of floating point
currently there really isn't a systematic / portable story for doing compile time reduction / evaluation for floating point numbers.
there are some folks in the larger haskell community who are working on high precision soft float implementations / modelling.
Once that work becomes available, might be worth exploring having something like that for doing controlled high precision evaluation of intermediate expressions in ghc proper.
