I wanted to add a long integer field in arcgis, but finally I clicked OK, and the field type became double precision again ~! What's going on here? Seek expert answers

You should modify the length of the field. When the length exceeds a certain value, it will become a floating-point type. You can check the document. I can't remember clearly.

I just tested it, and there is no problem when the length is 9, and it will become double from 10. Therefore, when building a long field, the length of the field should be less than or equal to 9.

It is helpful to search the help document for the conversion method when importing data.
