Tip & Bill Split Calculator

Figure out the tip and split a bill evenly among any number of people — with tax, an option to tip before or after tax, and an optional round-up so each person pays a whole-dollar amount. All arithmetic is done in integer cents, so when a total doesn't divide evenly the odd cent is distributed fairly (a few people pay one cent more) and every share adds back up to the exact total.
