You could also force it to always only look at 2 decimal places. If you are doing a calculation to say add two numbers (not likely where your math goes wonky, but it works just the same), instead of doing:

$sum = $a + $b

you can do something like:

$sum = round($a, 2) + round($b, 2)

The above example is in PHP, but I'm sure C has a similar function. This will round $a to say, 13.46 instead of 13.46000000 or 13.46000001234542 and will perform the math on that value.
