I have a script that inventories my ftp site for size and encountered the same problem. I have been using calc387.com. I have the values add to each other in kix as long as they are <1,400,000,000 in size. Then I shell out to calc387 with the current calc filesize string plus the kix filesize integer > 1,400,000,000. I even tried cutting the last 3 digits from the GetFileSize()... but calc did it faster, even though it is constantly writing/reading the harddrive. Maybe kix isn't only limited in mathematics by integer length, but also by speed?
