These three posts (here, here, and here) on the Batman question are certainly not answers to the original question. However, I'm unsure about what exactly to do with them. Here are possibilities I've thought of:
- Delete them.
- Convert them to comments on the question.
- Make a community-wiki post on the question, which will collect all of them together.
I like 3 the best. Simply deleting them would be entirely justified, I think, but a lot of people who see this question are going to want to try it out for themselves, and we might as well save them the trouble of typing out the whole thing. Also, with a community wiki post, anyone can add the equations as expressed in even more languages/systems, and it can be corrected / improved by anyone (this appears to be necessary: it seems stoicfury's and John Garner's answers don't actually work. I haven't tried Mark's suggested equations on a graphing calculator yet.)
What do people want to do? Any other suggestions than the ones above?
