It's a GHC extension, while realToFrac is Haskell 98.

realToFrac :: (Fractional b, Real a) => a -> b
It is actually defined as fromRational . toRational but GHC knows to
generate specialized code for par
In NumExts, there's floatToDouble and doubleToFloat.

Quick and probably stupid question:
If I want to convert a Float to a Double, should I use
fromRational . toRational
? It seems to work, but isn't this a bit weird? It took a while for
me to figure this out. I suppose they are rationals because of the
finite precision of Floats and Doubles?
Hi everyone
I've built GHC from CVS and I'm getting some odd errors about overlapping
instances. This is different from 6.0.1, but it's not obvious it is wrong,
so I'm probably missing something here.
The example is
class A x
class (A x) => B x
instance A x
instance B x
The new GHC complains th
