Re: [Haskell-cafe] Way to implement toFloat :: (Num a) => a -> Float

EatsKittens writes:

Is there a way to add a method to a typeclass like num to implement this concept? A function that converts any number to floats?

Does the following do what you expect? realToFrac :: (Fractional b, Real a) => a -> b realToFrac' :: (Real a) => a -> Float realToFrac' = realToFrac :: (Real a) => a -> Float Cheers, - Ben
