Yeah, so your program now does not work in debug for particular input data. What is the next step?

The next step when TheIDE debugger breaks is to solve the problem

But how? There is obviously a combination of input data that leads to FP exceptions. How are you going to solve it?

If you wanted to check the inputs before processing them, you would have to trace back all calculations back to inputs and do other calculations just make sure this particucal input dataset does not cause the problem.

That is the part I never solved and that makes me appreciate the idea of using NaN for what it was indended too.
