What's wrong with my definition of sqrt? user=> (defn sqrt [x] (. System.Math Sqrt x)) #'user/sqrt user=> (sqrt 4) System.InvalidCastException: Specified cast is not valid. at lambda_method(Closure , Object ) at AFunction_impl.invoke(Object ) at lambda_method(Closure ) at AFunction_impl.invoke() at REPLCall(Closure )
It works from REPL: user=> (. System.Math Sqrt 4) 2 Notice that user=> (sqrt 4.0) 2 works as expected. - Dmitry --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
