(defn float2 [f a b] (f (float a ) (float b))) (float2 + 1 2) => 3.0
(defmacro mfloat2 [f a b] (f (float a) (float b))) (mfloat2 + 1 2 ) => 2.0 ??? macro expend to last expression in list,right? (defmacro m2float2 [f a b] `(~f (float ~a) (float ~b))) (mfloat2 + 1 2) => 3.0 (defmacro m3float2 [f a b] (list f (float a ) (float b))) (m3float2 + 1 2) => 3.0 functions of macro only not evaluating args ? what's the difference between macro and call by name in other language? gerry --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
