Real numbers are stored internally as binary numbers, and have to be converted back and forth to decimals. There are other sources of innacuracies as well; in other programming languages you learn that you can't make a trustworth comparison (if A = B) involving real numbers (FoxPro has solved this problem for most cases).
You simply have to be aware of the limited accuracy, and use workarounds in some cases.
