You are right:
(class 0)
gives:
java.lang.Long

I don't know that I agree with that reason. Clojure numerics start from an
assumption of a 64-bit world, so numbers default to 64-bit types: long and
double, instead of 32-bit int and float. Java interop is one of the places
where this default can create a mismatch, since Java tends to use 32-bi

To avoid the performance penalty of automatic promotion. In dynamically typed
languages
with auto-promotion of integers you have to perfor
I have the following code:
(def intArr (make-array Integer 10))
(for [i (range 10)]
(aset intArr i (int 0)))
(for [i (range 1)]
(let [index (rand-int 10)]
(aset intArr index (int (inc (aget intArr index))
(for [i (range 10)]
(println (aget intArr i)))
I need to use
(int 0)
