Entering a Bill Total

Using the numeric keypad, enter 34.56. Just type 3456—the app will position the cents to the right of the decimal point. If you make a mistake, press the delete (Image) button to erase one rightmost digit at a time. The TextViews under the 15% and the custom tip percentage (18% by default) labels show the tip amount and the total bill for these tip percentages. All the Tip and Total TextViews update each time you enter or delete a digit.
