If I want to convert a Float to a Double, should I use
fromRational . toRational
realToFrac :: (Fractional b, Real a) => a -> b

It is actually defined as fromRational . toRational but GHC knows to
generate specialized code for particular types.
...
And similarly, (fromInteger . toInteger) is the right way to convert
the integral types?
fromIntegral :: (Num b, Integral a) => a -> b
