Here's the code for my personal calculator with lots of useful functions (and a couple that you probably won't need, like slowprint). It should work outside of Touch Lua, if you change around the configs. I'm working on an installer that automatically sets up the configs for your current device.(Installer on hold. Feel free to do it for me, anyone that wants to.)
