What is the maximum value of an unsigned 64-bit integer in English?
I'd say "two to the sixty-fourth minus one", personally.

I think the pluralizations need to be singular, e.g. "quintrillion", "quadrillion", etc...

@Eric J.: Thanks, I'd never realized that that was the case, though it fits with how numbers are written in newspaper headlines etc. Less worried about that mistake than that I wrote tree instead of three though...

In American English, at least, you don't say "and" except at a decimal point. I've heard Brits argue over whether saying "and" is a British English thing, or just plain wrong.

@Ken: so he wrote the answer in real English (English English) instead of American English. Good for him!

@aioobe: If you have 64 bits, there are 2^64 combinations of these, so you can store the values 0, 1, 2, 3, ..., 2^64 - 1. To see all digits of 2^64 - 1, ask Wolfram|Alpha. It does end with "15".

Where did you get 18,446,744,073,709,551,616 from?! In my universe, 2^64 - 1 = 18446744073709551615.

Thanks, I started linux and used bc typed 2^64 and forgot to subtract -1, fixed that

A:
(format nil "~r" (1- (expt 2 64)))
=>
"eighteen quintillion four hundred forty-six quadrillion seven hundred forty-four trillion seventy-three billion seven hundred nine million five hundred fifty-one thousand six hundred fifteen"

A:
About 18 million million millions
1 followed by 18 noughts
If you had this many paperclips, it about the same as 46 billion blue whales
It's only around 3 thousand million million sheets of paper stacked on top of each other to reach the sun.
Or "a lot"
Frankly, in English you aren't going to hear it on the street anyway. Your audience would fall asleep somewhere around quintillion.
