3.3V? or 3.333...V?

I was just curious...when a specification refers to a supply voltage or absolute maximum, etc. of 3.3V. Has the number been rounded to one decimal place and they actually mean 3.3333...V? Or do they actually mean 3.3V? Or is it irrelevent because of variance or does it every manufacture treat it differently?

Actually, what I really want to know is whether the 3.3V specification refers to 0.66*5V or (2/3)*5V.

THanks.

Actually, 5V is really 0.737*6.78426V
Seriously, there is nothing magic about 5V. 3.3V is just what it is.

HEhe

Hehe, ya never know
