Exponential Currency Denominations

See the previous (sliding scale drinks) idea...

If our currency was printed in exponential denominations ($2, $4,...$1024, $2048, etc.) it'd be real easy to pay for your sixth, seventh drinks even if you were smashed. Tipping 10% might get a bit complicated, but I know I'm not throwing in an extra $102.40 on a $1024 drink!

Sliding Scale Drinks [Worldgineer, Jun 21 2005]


       Two problems with this:
(1) Happy hour -- So much cash, so little time. and
(2) Promotions -- like in, "with every drink ordered you'll receive a ... " Damn! How happy can I be?

       So what is $1, $10, $100? Perhaps you mean *binary exponential*?
ldischler, Jun 21 2005

       But currency at the moment comes as 1: 2:5:10:20:50:100....etc (from 1p up to £50, or maybe beyond). (Actually yhis may not be true for US currency - is it?). <> This is not quite optimal, but is close to optimal and more convenient, and you need fewer different types of coin.

       The US has the same paper sequence: 1 2 5 10 20 50 100, but the 2 is hard to find. Anyway, there's already an exponential in there: 1 10 100.
ldischler, Jun 21 2005

       1:10:100... that would be "base ten" numbers. We live in a "base ten" world most likely because we have ten fingers (gents could have imposed a "base eleven" system but that wouldn't be fair). You can't raise one to any exponent to get ten. Binary is based on two to the N power (like my sexual stalling tactics, ahem!) where the maximum number of different values expressed would be two to the N power where N is the number of bits to store the value.   

       Okay - good for sliding scale drinks, screwing, and not much else.

       //You can't raise one to any exponent to get ten.//
[NG] You need a modicum of math here: 1 10 100 is 10 to the 0 1 2 power, just as 1 2 4 is 2 to the 0 1 2 power. Same thing—both are exponential.
ldischler, Jun 21 2005

       Quite true. I suppose that's why it's called "base ten". Perhaps I should cut back on the glue-sniffing...

       Known   Desired
------- :: -------
H : V      D : X
Glue !? I LOVE glue. (Multiply means (V & D) and extremes (H & X). Solve for x

       Oh, three problems (3) How to keep up with bets over the next round?
