Future release - Increase range of integers for "Do Arithmetic" CA

I want to determine if there is sufficient free disk space available for an installation.

The script “Get free space available…” reports 48307130368
When I create the script “Do arithmetic…” and attempt to subtract the disk space required from the above value, the Resulting value is just the inverse of the disk space required. This would imply the above value is being interpreted as zero?

%ResultingValue% = 48307130368 - 703950848
%ResultingValue% = -703950849

We’ll check this problem. Thanks.
