This is ambiguous: "while trying to reach resolution_check<8 and mX_check>0.1" If resolution_check is 2, then that means you've reached (achieved) the condition of "resolution_check<8". The correct way to indicate that an answer is perfect is to accept it, not to leave a comment. continue skips the remaining instructions in the while loop and begins the next iteration. So if resolution_check >= 8 or mX_check <= 0.1 then the condition is not true and it will break immediately.
