I use a calculator all the time - not for calculating a tip though. Sometimes I use bc (when I can't find my calculator in the morass of my desk). True story - the other day I was in a store and my total was $10.12. I pulled out a $20, and the cashier (probably age 23 or so) immediately entered $20 as the amount tendered. Then I said "Let me see if I have the $0.12." I did not, but I had $0.15 so I handed her $20.15. She literally froze in place with a classic deer in the headlights stare. I said "$10.03" She said "What?" I said "$10.03 is my change." She said "What?" I said "Just give me $10." She did not reply, opened the drawer below her register, rummaged around and came out with one of those giant key calculators, and with a look of dogged determination, did the calculation, looked at me and said proudly "$10.03 is your change." -- https://mail.python.org/mailman/listinfo/python-list
