Hi Vladimir,

>I am interesting in what is the best practice to deal with VFP rounding in calculation proble.

Actually, this has nothing to do with rounding. The problem is that 550000.815 is not a number you can store in a floating point value which uses a base of 2. That's the same as trying to display 2/3 accurately with a base of 10. You can see this without any multiplication and rounding by just printing:
