Google's Billboard Challenge

I have posted my take on the now so-very-old Google billboard challenge.

It was more of an excuse to brush up on certain skills, but this last week I've just been kicking myself and agonising over the fact that I decided to use the classical factorial formula to calculate e. That formula is evidently not suitable for what I was trying to do and seems inherently bounded for a stream approach.

There are rumours of the existence of a digit-extraction algorithm for e but I have yet to see it or if I have seen it, I have yet to gr0k it. Is it too much to ask for a simple damn formula or explanation for calculating the value of any digit of e without having to read through pages and pages of theory?

Evidently my math skills need much work.
