Nice. Two suggestions:

1. You could likely have auto-generated the callback stuff so you wouldn't have had to have it written out in each function.

2. You could have written the parameters and return values and equations in a Object for each function and auto-generated the inline docs and the i-prefixed functions. This would have gotten rid of more duplication that is present.

Thanks for the suggestions! I couldn't figure out a way to auto-generate the callbacks, but I'll keep that in mind next time! I'll definitely work on the second solution you proposed, I think that would actually reduce the duplications.

I'm deeply, deeply suspicious of the accuracy and stability of something like this--that said, bloody good job!

Thanks! We'll be working on fixing those things :) We've made it so it's easy to increase/decrease the accuracy, but the next thing we plan to do is to make the equations rearrangeable!

I'm just sort of curious how you folks are working around Javscript's lack of double precision or arbitrary precision for numerical stuff.
