【實用工具app】Simple RPN Calculator|最夯免費app-綠色工廠好玩App

This is a simple RPN (Reverse Polish Notation) calculator designed for basic mathematical calculations. It is designed to replace the four function algebraic calculator found on android phones. The calculator display shows the top four values on the stack (X, Y, Z, and T for those familiar with HP calculator terminology), and holds up to 46 more. In addition to the add, subtract, divide, and multiply functions, the calculator also includes a square root and power function.
