golden ratio.)

I can't read Mathematica well enough to figure out what number this is 
the continued fraction for. (It isn't sqrt(12500).)

Second, how does this relate to the golden ratio? There is no 
explanation or reference. (It appears the number approximates 100*phi, 
but there's still no detail - how accurate (actually equal?), how is 
the sequence of approximations derived, etc. etc.)
