In the source code, which is available here http://clojuredocs.org/clojure_core/clojure.core/%3E the value for one argument is set to true: (defn > "Returns non-nil if nums are in monotonically decreasing order, otherwise false." {:inline (fn [x y] `(. clojure.lang.Numbers (gt ~x ~y))) :inline-arities #{2} :added "1.0"} ([x] true) ([x y] (. clojure.lang.Numbers (gt x y))) ([x y & more] (if (> x y) (if (next more) (recur y (first more) (next more)) (> y (first more))) false))) Alan -- You received this message because you are subscribed to the Google Groups "Clojure" group.
