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

A Reverse Polish notation calculator for scientists, engineers and geeks.* Features *-quick start up. Really.-engineer style exponent display-large keys-9 memory store banks-no stack limitIf you don't know about RPN, read a Wiki article about it (there's a link in the App that leads to the site in your language).Instead of typing braces, you use a stack and perform operations on the stack items.(2+3)*5 would be computed:2 Enter (push 2 on the stack)3 + (add 3 to the bottom stack item)5 * (multiply stack bottom by 5)The stack now shows "25".RPN is much faster and easier for large, complex terms. Do yourself a favour for the rest of your life and learn postfix notation. It's easy, really.
