Dear Haskellers,
I just want to share an observation. I had to convert a Double to a Float
value in an inner loop of an application, and I used somethin like this:
xf = (fromRational $ toRational xd) :: Float
I think realToFrac is the function to use here, and this might be replaced
by double2Float by an optimizer rule. I think double2Float is from a GHC
package and thus one should avoid to call double2Float directly.
