When using the ChangeDetector to compare attribute values, decimal and datetime values create false-positives due to precision (i.e. 10.00 vs. 10.0001). Perhaps comparison of decimal values could be done via abs(value1 - value2) > epsilon. The user could enter the epsilon value. Dates vs. DateTimes could be handled similarly.

ChangeDetector alternate comparison of decimal and datetime values

Was just pulling my hair out with this today. It wasn’t a matter of close precision like the post but I inserted into SQL Server from an Oracle dataset and because of differences in how the data was represented by each vendor, it wouldn’t match. 25.8 <> 25.80000000 according to ChangeDetector but was flagged as a duplicate by DuplicateFilter.
I ended up using a regex replace in an attribute manager to trim trailing 0s, but more control over decimal and datetime matching is worth an upvote!
Cheers, Ken
