Plus some others like a googol (10^100), centillion (10^303) and googolplex (10^googol). All of these last numbers are so high that if you had that many dollars (or the equivalent of in other currencies, using the largest denomination), they couldn’t possibly exist physically because the Universe doesn’t have enough matter (estimates are around 10^80 atoms).
I am no expert, but aren’t most people in Britain more familiar with the “American” (short) scale for their day-to-day use? I prefer the short system because that’s what I was taught and while I might worry that it comes across as American hegemony, my belief that short is better is strengthened by the fact that the mentioned centillion is called quinquagintilliard or a thousand quinquagintillion in the long scale. :eek:
Hey, do you want to trade a Zim $50 bill for a 100 Trillion dollar bill? When I was in Zimbabwe in 2002 the exchange rate was $400 Zim to one US dollar. At the end of the week it was $600 Zim to one US dollar.
I think I actually have a Zim penny lying around here somewhere!
The only fundamental physical limit on hyperinflation is how quickly you can redesign the currency to tack more zeroes on, and how long it takes the ink to dry.
Although, really, with electronic payments, that’s not even a limit any more.
