Perhaps you should step away from your PC for a bit? Christ.
Arguing that somebody shouldn't expand a large number because you personally now perceive this number differently and therefore it is intellectually dishonest is a bit of a squirrely argument, don't you think?
We're all capable thinking humans here. That isn't to say that smart people cannot be swayed with rhetoric and such, but don't you think that the same argument you're making here could be made against compressing such large numbers? Maybe expanding that number isn't so much exaggerating its value as it is simply impressing upon us its true enormity.
$3.2B ($3,200,000,000.00) is a lot of fucking money, after all. For anybody.
$3.2M would be a truckload of money too, but on a Google scale, "This number is really enormous!" is a weak argument. $3.2B is less than 1% of their market cap. Relative terms are much more important than "how many zeros"; why, just recently, Google took a $150M loss in Q3'2012 on the Motorola division. They aren't afraid of 9-figure losses. Thus (IMO) $3.2B being a large number has little bearing on whether or not Google would be willing to take a writedown on Nest, for the right reasons.
Eh, guess we're going to agree to disagree there. Dollar figures having two decimal places at the end is pretty much a standard. If they included 3, yeah, that would reek of shiftiness. On top of that, all of the press releases I see don't even include the full amount written out, just "$3.2B".
This is known as "rhetoric". The art of making a point. For sure the zeroes are being written out in full to make the number look more impressive. And the cents are given for exactly the same reason! What else would they be there for?! Writing out large numbers in full is a valid tactic to make a point, just as is hiding all those zeroes away behind an abbreviation.
decimals doesn't have commas, if you want to add 12 digits of precision then you should have to write: $3,200,000,000.000000000000 , also when writing down a money amount, those two extra digits are for the cents(exactly 2 digits of precision), It would be ultra weird to write with 1 or 3 digits of precision, or zero for that matter.
