Either way, it's got a weird profile (increasing, but not monotonically): user=> (doseq [n (map #(Math/pow 10 %) (range 10))] (time (dotimes [_ n] (Math/ceil 0.1)))) "Elapsed time: 0.238077 msecs" "Elapsed time: 0.007346 msecs" "Elapsed time: 0.030386 msecs" "Elapsed time: 0.255107 msecs" "Elapsed time: 10.399609 msecs" "Elapsed time: 5.677462 msecs" "Elapsed time: 1.423789 msecs" "Elapsed time: 9.779539 msecs" "Elapsed time: 65.505686 msecs" "Elapsed time: 651.333768 msecs" nil -- You received this message because you are subscribed to the Google Groups "Clojure" group.
