Most likely you have a bug in your program. Have you looked at the
results of your calculations before writing them out? Since you have
provided no data, we can not reproduce what you are doing to show
where the error might be, or the correct way of doing it. In almost
all cases, if you think you are getting weird resutls, it is because
your calculations are producing the weird results. It is time to
learn "debugging 101"; there are plenty of tools that will let you
examine your results and determine where your errors are.

What is the problem that you are trying to solve?
Tell me what you want to do, not how you want to do it.
