Calculating x,y coordinates returns imprecise values

I am using Calculate Geometry to populate attribute fields for a point feature with x,y coordinates in decimal degrees and the values that I am getting do not seem to be very precise, in some cases having only 3 digits to the right of the decimal (e.g. 43.358).  But, when I select the point using the Identify tool, the location coordinates shown are slightly different, and show all 6 digits to the right of the decimal.  I have tried using both the coordinate system for the data frame and the feature (both NAD_1983_UTM_19N). 

Why doesn't the calculate geometry function return the same values as the Identify tool? 

This is true of even the values that include 6 digits to the right of the decimal.
