I am trying to edit an attribute table in ArcGIS 10.1 and so far have been unable to keep it from rounding to whole numbers. Even when I manage to "pad with zeroes" using the numeric settings, it will round to 6.0. I have tried the Editor > Options > General method as well. My decimal places are currently set to round to 6, but any data I enter rounds to a whole number. My field is set to "Long Integer". What obvious solution am I missing?
