Question

Why is StatisticsCalculator returning null for min and max?


Badge +1

Hi, I’m having an issue with the StasticsCalculator returning some nulls for min and max. And also some unexpected rounded max values.

 Input data

 

I’m calculating statistics on avg_dur field and grouping by SEG_ID. Unexpected results highlighted.

 

The avg_dur field is data type real32. For some reason changing the data type to real64 results in the stats being calculated as expected.


The ave_dur field was originally imported from an esri shapefile with data type .

Wow, ultra weird. Sounds like a bug. Is there anything in the log file, e.g., warnings? What version of FME are you running?

Hi @b-rad Unfortunately this is a known issue, filed as FMEENGINE-82162.  I did find a crazy work-around, which was to add a Creator before the StatisticsCalculator and disable the connection between them.  I don’t guarantee this, but do let me know if it works for you. :^)

Thanks @DanAtSafe. The Creator work around doesn’t seem to help me. But as mentioned I can change to real64 and as a workaround.

 

@virtualcitymatt I’m on 2023.2.1.0 but can also replicated on 2024.0.
