I can't speak for banks in general, but software developers within banks (etc) tend to just continue SI prefixes - cent, mille, micro, nano.
This could explain my preference for SI notation. :-3Edit:
In fact I was pointing out that no one had thought of what to call anything below .01.
Actually, we have: https://en.bitcoin.it/wiki/Units
There's just some disagreement about whether we should really use the units on the wiki or not. Especially that bitcoin-bong one...
Well then, question answered. Thanks. I didn't see it.
*Awww c'mon .. let the stoners have their fun. It's not like they don't see innuendo everywhere anyway.
