I just got into the EXACT SAME ISSUE and it's mind boggling why ArcPo cannot (or refuse) to make this simple feature available.
"....It turns out that this other employee (I won't name but he was great as well, seriously!) was the person that argued for changing it to one decimal place (who could have predicted that?). His reasons were sound, though shortsighted (my opinion)....."
Hopefully I am wrong, but such opinion from that ESRI employee simply make me ANGRY about ArcPro, and drive me more and more a "ArcMap Desktop loyalist". I understand he may have a "high road" in his mind (such as forcing us to put extra effort in order to develop so-called good GIS practices), but those kind of Holier-Than-Thou attitude is not going to win more genuine convert to ArcPro. If ArcPro is a real upgrade, why not keeping the original feature that make ArcMap Desktop great?
Seriously, it is THAT hard for them to add/fix such minor features, which would make thousands of ArcPro users life such simpler?
Sorry for the ranting, but I second the cheers for Brian on advocating this minor but important issue on our behalf. Hopefully they can listen. Thanks again for everyone that bring this up!
