Yes, I wrote my message too quickly, you're right that some form of rounding is needed if you want to make sure to use integer addition; multiplying the numbers by 100 is not always sufficient to get proper integers.

Having said that, I still think that using just printf (or sprintf to convert the results and store them in an array) on the final result is probably sufficient to get the right precision (unless you're really adding huge volumes of numbers).
