User talk:Michael Chuquet/Hexadecimal billion
This discussion of the significance of the term "one billion hexadecimal" had been established at the origin between the user IP 81.57.112.41 (later called user:Michael Chuquet, that's me) and Ian, user:Icairns on the user talk page of "Binary prefix". The contents of this talk (17 Aug – 3 Sep 2004) were transferred on a "archieved" page called Closed talk: section Hexadecimal Billion in Talk:Binary prefix Talk:Binary prefix/Hexadecimal Billion.
I summary my point of view :
The hexadecimal billion equalizes sixteen power ten according to Michael Florencetime (page on fr.wikipedia.org).
Myself, Michael Chuquet, I approve this definition of the "hexadecimal billion", since it is (1024 x 1024) x (1024 x 1024).
The hexadecimal numbers should be grouped modernly (surprisingly, however correct-proves) by five digits.
For example: The internal 64 bits bus, that's 2 power 64 or F FFFFF FFFFF FFFFF units and the zero. "Sixteen trillion" hexadecimal units.
Thus sixteen power six (equal 16 777 216, also equal 4096 power two) is "sixteen million hexadecimal", written for example: "0x 10 00000"
This modern hexadecimal numeration supports the use of the original long scale in the decimal numeration.
The billion binary
Also the number "one billion binary" (= 2^40) has the same value as "one billion hexadecimal" (= 16^10).
Example : One billion binary minus one. This is (in hexadecimal) FFFFF FFFFF units.
In binary that's : 1111 1111 1111 1111 1111 : 1111 1111 1111 1111 1111 This number can be read :
Thousand one hundred onety-one quadri-myriad,
thousand one hundred onety-one tri-myriad,
thousand one hundred onety-one bi-myriad,
thousand one hundred onety-one myriad,
thousand one hundred onety-one million,
thousand one hundred onety-one quadri-myriad,
thousand one hundred onety-one tri-myriad,
thousand one hundred onety-one bi-myriad
thousand one hundred onety-one myriad,
thousand one hundred onety-one units.
So it's showed : "One billion binary" = "one billion hexadecimal" = "one billion (long scale) x 1.099511627776"

Billion, billiard, billards
Wrong, on quite a few points. I may add to the discussion, later.
Hexadecimal grouping is almost always in groups of 4, both for computer analysis reasons (16-bit, 32-bit, and 64-bit words), and because it's logically a binary system, so the number of digits in a group should be a power of 2.
"Billion" is universally 109 in English; the long scale is primarily of historical interest, except for borrowed words in non-English languages. See the long scale article for more information. Whether or not the long scale is more logical, it isn't used in English.
Are you claiming (spiritual) decent from Nicolas Chuquet, who is attributed with the first use of words related to "billion" and "trillion" in French?
