Calculate Geometry Attributes with Specific Decimal Points

ABishop — Thu, 30 Sep 2021 15:17:39 GMT

I am using ArcGIS Pro 2.8.2 Model Builder. I have been working on a model that makes a feature layer based on a selection criteria then calculates the geometry attributes of that feature layer's acreage field. The only problem I am facing now is that when I check the feature class and the newly calculated acreage, it is a decimal with 6 decimal places. I need this to be 2 decimal places. Any suggestions on how to accomplish this? Any help will be greatly appreciated! See the model's python code below.

@ABishop does the following guide help? https://support.esri.com/en/technical-article/000025170

Hello David,

I am aware you can set the field properties to display the acreage field with two decimals and also do this with labeling functions, but that does not change the raw data. I need the raw data that is calculated by the model to produce the output with two decimal places.

@ABishop but the Round() function will round your result to N decimal places.

Where would you insert that in the model python code?

like this at the end?

round(DBO_Parcels_Layer_2_, 2)? At the end of the script?

or....

round(DBO_Parcels_Layer, 2) ??

@ABishop im not entirely sure if you can add that into the calc geometry process directly, but you could add a field calculator process after this and just state that:

DBO_Parcels_Layer = round(DBO_Parcels_Layer, 2)

OK... I think I know what you are suggesting... I put it in the code below. I apologize but I am not a pro at programming... Can you check it out and let me know if this is accurate? If I am missing something?

or something like this at the end?

round(DBO_Parcels_Layer_2.GIS_ACRES, 2)
