I've got a bunch of tables and the last digit of all the numbers need to be replaced with zero and I'm not able to figure out the code to make it work. I have numbers ranging from 1 to 20,000 so the comma will have to be taken into consideration. The closest I'm able to get is having a zero added to the very end, not replacing the last.

So the columns should go from this: 3,271 1,559 1,712 12 279

To this: 3,270 1,550 1,710 10 270
