Numbers in the novel (small arrangement, small knowledge, you can not read it)

[[[In ancient China, there are three systems for counting large numbers of more than 100 million yuan: this is contained in the book "Recording of Numbers" in the Eastern Han Dynasty of China.

The first is the upper method, which is the self-multiplier system: ten thousand is billion, billion is trillion is trillion, and trillion is Beijing. This system has also been adopted by Archimed in Greece; 10^4=10,000, 10^8= billion, 10^16=mega, 10^32=Beijing

The second is the Chinese method, which is the ten thousand advance system, all with ten thousand increments: trillions of trillions of Jingzhao tiao gully (next to the soil) Jianzheng load ┅┅┅ (thousands are trillions to trillions of trillions for Beijing ┅┅); 10^4= ten thousand, 10^8= billions, 10^12= trillions, 10^16=Beijing

The third is the following method, which is a ten-entry system, all of which are progressing in ten: trillions of trillions of Beijing zom ┅┅ In modern times, until the liberation, the ten-entry system was still popular in China, that is, a ten-thousand-thousand-thousand-tight (next to the soil) stream is reported, all of which are ten-in, 10 trillion is 100 million, 1 billion is a trillion, and 10 trillion is Beijing... ; 10^4=10,000, 10^5= billion, 10^6= trillion, 10^7=Beijing

The "megabytes" used in modern science and technology belongs to the third law, that is, 10^6, that is, millions. For example: megaweek (MHz) megohm (MΩ) megawatt (Mw) ┅┅; while the modern "billion" belongs to the second kind, that is, the Chinese method (also consistent with the "billion" in the first method). 1.3 billion is equal to the 8th time of 13 times 10, not the 5th time of 10.

In general, in order to avoid confusion, "megabytes" is only used for 10^6, and 10^12 is expressed as "trillion". No matter how big the number is, use "thousand billion" "thousand billion" "billion" "billion" "billion" ┅]]

The counting method used in this book belongs to the second method. Chinese method: tens of millions is trillions of trillions for Beijing. There are many data in the book. Tens of thousands are generally replaced by W, hundreds of millions are not replaced by letters, and B is replaced by B. As for the Beijing after trillions, the value of this unit should not appear visually.

There is also the problem of cosmic coins in the book: you can imagine that the price of food will definitely change a lot in a thousand years. Simple, low-end food may only need a few cosmic coins, more than a dozen cosmic coins, and high-end food may be tens of thousands or millions. Reading books, I like to compare the coins in the book with our personal coins, which is difficult to compare, because the value of various items in two different eras is different, and the use of people's money is also different.
