Different result of operator precedence in Java and Python

I notice that I have two different result when I compile this operation in java, and python. 

10 / 3 + 2 * 4 / 3 - 3

result in java = 2.0
in python = 3.0

I also execute this operation in many calculators and the result is 3.0 can anyone explain how java deal with this?

double var = 10/3+2*4/3-3;
System.out.println(var);
Solution

  • The expression components will be evaluated as integers, i.e. intermediate values are truncated (10/3 evaluates to 3, 2*4/3 evaluates to 2 and so on).

    Changing to the below will result in 3.0:

    double var = 10.0 / 3.0 + 2.0 * 4.0 / 3.0 - 3.0;
