Close to 8/5. As you rightly say, it's derived from the Fibonacci series,
being F_n/F_(n-1), so the higher the numbers used, the better the
approximation. IIRC, after about the 20th term it starts to get pretty
much invariable for day-to-day purposes, i.e. 1.6180339, give or take.
Also, for my money, "numeral" means a representation of a number that is
not spelled out in words. "7" is both a number and a numeral, whereas
"seven" is just a number.
