You often have to do bit of manual coercion to make things work nicely with
the whole set of possible Clojure numerical types. Fortunately there are
plenty of built-in functions in clojure.core to help you do this.
In your specific case I would do:
(.add (Complex. 1.0 2.0) (double 2))
This

Hi Alan
Excuse me if I didn't understand your question, but I think a type hint
would solve. Maybe you could abstract this for the final user in Clojure.
(.add (Complex. 1.0 2.0) ^double 2)

performance, measure the result with a benchmarking library like Criterium.
