I am trying to add X and Y data from a previously geocoded data set (excel file). The process is a success but the problem I am facing is for some reason ArcGIS is rounding to the tenth place a very important identifying variable. I am converting the original results to a shapefile because I need to run a spatial join with the data. It appears that when converting the original results to a shapefile ArcGIS is rounding the variable of interest. Is there any workaround or way to stop ArcGIS from rounding my data?
