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

Ah, I had no ideal the real typeclass existed, that completely solves my issue. On 12 December 2013 20:39, Ben Gamari wrote:

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
