The funny thing is I often do that for a different reason. I would call them spurious digits. Since they are not measurements, but integer counts used to calculate percentages I think I am OK on significance, but not so much on spuriousness.
I occasionally dig up old stuff I did, like this, where, for some reason, I did not over-ride the default formatting in Tableau (BI software I often use instead of a spreadsheet). As the woman who edits the stuff I write for work can attest, I sometimes (often?) miss inconsistencies in formatting and phrasing in my own work.
Feel no conflict. We can all use good editors.
And since I cannot be responsible for disturbing Mr. Valentine's eternity, I have reformatted. RIP, good man.
