guneric3: Example: 4 folks share $32 worth of pizzas; tax is 6%; wish to give a 15% tip: Calculator splits it at $9 per guest; waitress ends up with $2.08 tip - a meager 6%. A big calculating problem here... actually worthless.

rictangle: Quick and easy to use, comes in very handy if splitting the bill.

cleoo: The tax rate is fixed at whole percentages. It can't be adjusted to decimals (e.g., 8.25%...)

dondiego89: Terrible. Not the least bit understandable.
