Take the number, subtract its whole part to get something less than 1, 
then invert it to get something bigger than 1, and repeat.

You will get a list of characteristic numbers that can be used to make 
good approximations real quick by doing a+1/(b+1/(c+1/(d+1/(e+etc...))))

But unlike what this latter formula looks like, you don't even need to 
keep a list containing values a b c d e etc... because there's a simple 
shortcut so that you don't have to start with the innermost parentheses.
