I can do that, but it does int x = Integer.valueOf(12).intdiv(Integer.valueOf(2)).intValue(). So there is still the overhead of boxing and unboxing, which doesn’t exist for other primitive operations, and intdiv itself performs some reflection magic as well. What I’m wondering is if Java is strictly required if performance is a concern with division.

If I do: (int)(12/2) Then it coverts 12 and 2 to Integer objects, calls a method that performs BigDecimal division, then calls “as int” (not just intValue) on the result, which itself does instanceof checks. I tried intdiv, and it is more efficient, but it still converts to and from Integer objects so that it can do A.intValue() / B.intValue(), and storing that result in an Integer itself. I see if I just do 12 + 2, it does a true primitive operation in the bytecode. Is there any way to perform primitive division in Groovy the same way it is done in Java?
