Sometimes precision (and thus data) needs to be destroyed. Say you owe me $1,000.211 and write me a check for $1,000.21

Do you still owe me a tenth-of-a-cent? Even if you do, does anyone (me, you, the taxing authorities) care? In fact, does anyone want to go through the effort of maintaining that debt? Even if I repeat this with 100,000 customers, I'm out $100. Again, does anyone care?
