This tip calculator is good when adding the tip to the bill on a credit slip. Easy to get the total wrong in dim lighting with bad eye sight even without a few drinks. There is a math error on this app: Bill $100.10 @25% shows $25.02 tip and $125.13 total. Fixed this on my own tip app https://wwwapp.net/tip https://wwwapp.net/tip. The tortured javascript is listed in the source. This is in case anyone actually tips 25%. There are a lot of people out there that could use it.
