The most annoying issue with EclipseME for me was the "broken" debugger, which just wouldn't start.

Well, building on what Niall Ryan started, if performance is an issue, you can take this one step further by optimizing the math and encapsulating this into a class.
So we'll start with a bit of math. Recall that 800 can be written in powers of 2 as:

Contrary to Patrick's answer, C++ has no `^^` operator for performing a short-circuiting exclusive or.

However, Patrick's warning about non-`bool` "Boolean" types holds e... |
