If you've seen old (English?) documents, you might have seen that they used two forms of S, one of which looked like an "f" or an integral sign.
Here's why
Google freaks, I challenge you to find a page with a better explanation.
Btw, to this day, it seems the British like to write their numbers floating around, with for example, the loops of "6" and "9" aligned and the 1 as "I", including a small, round "0" and the decimal point in mid-height (higher than most of the "9").
Oh, and the Dutch write funny "8"s, which look kind of like a cursive "g" with loose ends.
Americans write "9"s with a tail straight down (I learned this from my PalmPilot), and if their "1"s have an upper tail, then they MUST have a "base" otherwise it would be interpreted as a "7" (not so in Brazil, where "7"s must necessarily have a slant).
Btw, does anyone still cross their "7"s?
