Ronald, There was an issue with a math library in 4.6-4.8. If you try that in 4.4 or 4.10, that issue isn't there. If the bug tracker is up, you should be able to find more information on it.
The issue was a problem with the round function, if I remember correctly and could cause the very problem your seeing. My examples were with squares on squares. John "R.
