【實用工具app】Calculator|最夯免費app-綠色工廠好玩App

Calculator is a simple app for most everyday calculations. Calculations are done in order from left to right. It features

• A basic calculator akin to the physical number crunchers.

• A quick tip calculator. Slide the percentage bar to the extent you wish to tip, enter the amount on the check and hit percentage button to get the tip. Once you set the tip percentage, the app remembers it until the next time you wish to change it.

• A history of all calculations performed in a single session, accessed by clicking the calculator’s number display. Clicking any item in history reintroduces that calculation into the main screen. All history items can be purged with a single tap.
