There must be something wrong in your code, or probably the lenght of your fields.

What I mean is that if your exchange rate is a memory variable, there should not be any problem, as the memory variables are automatically adjusted to the whatever decimals they need, but if you are using tables as the data source, you need to have a lot of decimals in those fields in order to create large & accurate calculations, (Up to ten decimals).
You could also use the ROUND() function to force numbers to be rounded to whatever decimals, and you will always get the same result.

If you want send me your code to my e-mail, and after I analize it, I will send you an answer
