Hi,
Someone more knowledgeable than me should correct me if I'm wrong
(and  forgive my noobishness ☺ ), but I think that the proper way would 
be

typedef typename internal::traits<Derived>::Scalar Float;


(with an up-to-date Eigen, i.e. after the ei → internal:: renaming).

Best regards,

Bernard
