| ### 4.5.3 int operations `++` changes its operand to its successor, is itself no int expression `--` changes its operand to its predecessor, is itself no int expression `+` addition `-` negation or subtraction `*` multiplication `div` integer division (omitting the remainder), rounding toward 0 `%`, `mod` integer modulo (the remainder of the division `^`, `**` exponentiation (exponent must be non-negative) `<`, `>`, `<=`, `>=`, `==`, `<>` comparators Note: An assignment `j=i++;` or `j=i--;` is not allowed, in particular it does not change the value of `j`, see Limitations. Example:
      int i=1;
      int j;
      i++; i;  i--; i;
    ==> 2
    ==> 1
      // ++ and -- do not return a value as in C, cannot assign
      j = i++;
    ==> // ** right side is not a datum, assignment ignored
      // the value of j is unchanged
      j; i;
    ==> 0
    ==> 2
      i+2, 2-i, 5^2;
    ==> 4 0 25
      5 div 2, 8%3;
    ==> 2 2
      -5 div 2, -5 mod 2, -5 % 2;
    ==> -2 -1 -1
      1<2, 2<=2;
    ==> 1 1
