Thank for your proposals to improve Haskell's numerics. We have long needed someone who was willing to devote some time and attention to this area.
Can I interest you in a number of open tickets?
#4101: constant folding for (**)
#3676: realToFrac conversions
#3744: comparisons against minBound and maxBound are not optimised away
#3065: quot is sub-optimal
#2269: Word type to Double or Float conversions
#2271: floor, ceiling, round :: Double -> Int are awesomely slow
#1434: slow conversion Double to Int
All are accessible as http://hackage.haskell.org/trac/ghc/ticket/4101, etc. All need love.
