Times New RomanA query for those
less mathematically challenged than me
(ie just about everyone).
In the JoongAng story below, I'm puzzled why the new mega-unit
should have 13 zeroes, rather than 12 or 16.
It's not a new mega-unit, I don't think. I've known of the kyŏng
[Seoul경, 1x10^16] for as long
as I've known of the cho [Seoul조,
1x10^12].
Times New RomanIf I have it
aright, the man/ok system - whose use even in official
English-language websites etc traps many an unwary foreigner
brought up on three-based Western thousands/millions/billions
- proceeds in quasi-binary units of 2 and 4, thus:
baek 100
man 10,000 (a hundred hundreds)
ok 100,000,000 (ten thousand ten
thousands)
It gets even murkier when a Brit and a Yank talk about it, since they
can't agree on a billion, trillion, quadrillion, quintillion, etc.
Times New RomanThat is already
plenty big enough. But the ROK's perverse refusal
to do to the won what de Gaulle did for the franc in 1959 - ie create
a new won, worth 100 old won - means they now need mega-numbers;
hence the gyeong. Fair enough.
Such a system is easier said than done (and cheaper said than done).
And I suspect that if they did change, they would lop off just one
zero, not two, keeping it much closer to the Japanese yen with which
it often dovetails and fishtails.
For now I would be satisfied with a 100,000 won bill being made. They
can even put Shin Saimdang on it.
Times New RomanBut why
13 zeroes?
Times New RomanOK,
ok ok (16 zeroes, ten quintillion!) is beyond need,
or grasp.
But why not 12 zeroes (10,000 cubed), ie the western quadrillion?
Has 13 some mystical significance? Lucky for some?
I think someone has miscounted the zeroes/places (and I hope it's not
me).
The article mentions an amount of 27 quadrillion won (26 billion US
dollars).
In the US system, that would be 27,000,000,000,000,000 (27 followed by
15 zeroes; or, to put it more usefully, 2 followed by 16 places).
In East Asian 10,000-based numbering, that would be 2 7000 0000 0000
0000 (2 followed by 16 places).
In mathematics and science, numbers followed by multiple zeroes are
routinely written as a SINGLE DIGIT, zero through 9, and usually
followed by a decimal point and some digit(s) afterward. Thus, 2597
would be written as 2.597 x 10^3; 32,438 would be written as 3.2438 x
10^4.
27 quadrillion would be written as 2.7 x 10^16 (16 being not the
number of zeroes, but the number of places following the first single
digit—the 15 zeroes and the one 7).
16 places would be the fourth power of man (as in
Seoul만/萬, not humanity, though these
numbers do represent the power of consumers). The fourth power of man
would be kyŏng:
1st power: man
[Seoul만/Seoul萬]
= 10,000 ^1 = 1 0000 = 10,000 (Seoulten
thousand)
2nd power: õk
[Seoul억/Seoul億?]
= 10,000^2 = 1 0000 0000 = 100,000,000 (hundred million)
3rd power: cho
[Seoul조/Seoul兆]
= 10,000^3 = 1 0000 0000 0000 = 1,000,000,000,000 (trillion)
4th power: kyŏng
[Seoul경/Seoul京]
= 10,000^4 = 1 0000 0000 0000 0000 = 10,000,000,000,000,000 (ten
quadrillion)
27 quadrillion is 2.7 times "10 quadrillion" (1 kyŏng) so it's 2.7
kyŏng.
But most definitely it is sixteen places following the 2.
Times New RomanI learn from
Wikipedia (see below; sorry I don't know how to paste characters)
that Chinese has words for both of the above (12 and 16 zeroes).
But otherwise I'm outnumbered, and can only shriek: OOOOOOOOOOOOO!
Can anyone figure it out?
Let's just hope they fix the currency-zero issue by the time the
economy gets to being one mole (6.02 x 10^23, give or take a few
quintillion). And there is, of course, already a Korean word for this
(used frequently at KAIST, I'm sure):
Seoul몰.
For reference, here's the original article from the Joongang Daily:
ㅡ It's getting tougher to count the zeros in talking about the Korean
macroeconomy, and some statisticians probably wish the won were worth
only 10 or 100 to the dollar instead of over 1,000. All those zeros to
describe an economy the size of Korea's has forced a new numerical
term into use: one gyeong, a unit of 10 quadrillion.
The Bank of Korea said yesterday that the sum of all transactions
through domestic financial service companies reached "2.7 gyeong won"
or 27 quadrillion won ($26 trillion) last year. Transactions in
derivatives are also more than a gyeong's worth every year.
A Bank of Korea official said that when Korea's broadly defined money
supply reached 1.3 quadrillion won, he had to refer foreign bankers to
a dictionary to confirm to them that there was such an English word as
"quadrillion."
