一个计算器应用程序，旨在做一完整的图形计算器能做的。（仍在发展中）

An android calculator app that aims to do everything a full fledged graphing calculator can do. This project has been orphaned. No one is working on it. The developer has realized that the project is too big for one person. The entire project needs to be rewritten as when the project was started the developer had no formal computer science education and the code is written poorly. A lot of cool things could be done if this app was rebuilt from the ground up, but one person cannot do it.
