【實用工具app】RePNCalc Free|最夯免費app-綠色工廠好玩App

Crunch your numbers with the rpn calculator that fits right along side every other iOS 8 app! Don't get held back by the conventions of traditional, keyboarded calculators that can't update their buttons with new functions without the use of a shift key! Use technology from the future, like swipe gestures to change key layouts or touching and holding a stack item to get a popup granting a range of options.This calculator app uses the alternative method called "reverse polish notation" to provide input for calculations. For the curious, check out http://en.wikipedia.org/wiki/Reverse_Polish_notation for more information.The full version contains full functionality in addition to complete support for iPad, iPhone, and iPod touch. The free version allows you to sample the basic functionality of the app on iPhone and iPod (it will work on iPad as well, but with the iPhone upscaling).
