Like the concept, but I'm on Windows so I'll try out some of the alternatives mentioned in these comments.
My solution for Windows has been the NppCalc plugin for Notepad++. It is not quite as advanced, but does have a lot of functions that the alternatives don't (like some common encryption algorithms which came in useful recently)
