Q: Did you leave your calculator at home before entering your Geminispace capsule?
Perhaps not, but in case you did, there is now a Gemini arithmetic calculator to get you out of your pickle.
This is another CGI test application - I wanted to test the process of getting input from the user.
The calculator itself:

You should be able to throw any simple arithmetic calculation at it, including brackets, scientific notation etc. It will try to help you out if you feed it nonsense or invalid input. It doesn't have any inbuilt functions like sine, or mathematical constants like e, i, pi though. So it's kinda basic, but fun.
There is also a short blog post walking through the high level logic
