American descent
That $ is a combination pattern of U and S (Uncle Sam, USA), which is used when marking the money bag by mailing the post-American Dutch letters. U and S are similar to the double-dash "$" mark in history: the bottom of U disappears in the bottom curve of S, leaving two vertical lines. This two-stroke dollar symbol refers to the United States. Money. Therefore, the one-stroke design may be modified from the two-stroke design to represent American currency. The main popular atlas of the philosopher Ayn Tian ridge's novels dismissed this idea, ignoring the fact that signs were already used during the British colonial period, when the word "America" did not exist.
The origin of Rome
The symbol of the dollar can be traced back to the most important Roman coin, and Cestes took the letter "hs" as its currency symbol. When superimposed, these letters form a dollar sign and two vertical lines ("the horizontal line that merges into' s' and' h'). This explanation was widely abandoned, although the influence trend of the neoclassical Roman Republic was obvious in the design of other early American governments, such as the Capitol and the Senate Building.
Temple of Solomon
The two vertical lines represent Boaz and Jacin, two worship pillars in the original Solomon Temple in Jerusalem. According to this idea, the symbol of freemasonry, such as God in everyone's eyes, appeared in the United States. Currency; However, they are not in 1785.
Germany Taylor
This is obtained from the logo of Taylor used in Germany. According to Ovason (2004), in one type of Thaler, one side shows the persecuted Christ, and the other side shows the A snake hanging on the A cross and the head letter NU adjacent to the snake, and the other side of the cross is 2 1. This refers to biblical numbers, chapter 2 1 (see Nehushtan).
Silver unit
During the colonial period before the American War of Independence, the dollar symbol was always used. Because Spain's "eight pieces" pay for goods and services for a common purpose, prices are often quoted in silver units. When quoting, the capital letter "S" is used to represent silver, and the capital letter "U" is written on it to represent the unit. In the end, the capitalized' u' was replaced by a double vertical military service sleeve.
Other theories
Another possibility is that it got 8/ 8 shillings from the British notation, and mentioned that Spain's 8 reais were coins (eight pieces) and later became dollars. Others from Portuguese cifr &；; Atildeo logo.
A common explanation is that the symbol is obtained by the number 8, which means "eight blocks". The Oxford English Dictionary reserves it to 1963, which is the most likely explanation, although the latest version questions it.
Another explanation is that the symbol of keeping the dollar comes from the imprint (or at least inspired by it) of Potosi silver coins (real or "eight pieces") minted during the Spanish colonial period. The imprint is formed by overlapping the letters "PTSI", which is undoubtedly similar to the unique symbol of the US dollar (see figure). Potosi mine is recognized as the largest silver mine selection in history. Silver coins were cast in Potosi, the United States during the colonial period, and were used for general purposes, and their imprint was widely recognized. The insufficient interpretation of the bearing symbol represents the snake, the guard bag, and has been used in Tyronia notes.
However, the symbol of the dollar may also have originated from the Greek god banker, thief, messenger and liar: Hermes. Besides the crane, one of his symbols is a peeled hassell stick with a white ribbon swaying on it. Stupid people often mistake these for snakes. In this way, the vertical line (|) may be a hassell stick and the s may be a ribbon.
The first statue of the dollar symbol
According to a plaque, the first dollar symbol in St Andrews, a Scottish autonomous city, was cast in a lead foundry. John Bain, a Scottish immigrant from Philadelphia, is 1797. John Bain and Alexander boarded in a house on South Street in St Andrews. Wilson is a Scottish type of father. On the other hand, because the dollar symbol is almost one of the few symbols in computers, its literal meaning is rarely needed in programming languages. Computers use the $ character for many purposes that have nothing to do with money, including:
"$" uses CP/M as a string terminator, and then it is also used at the end of symbol lines of all versions of 86DOS, PC-DOS, MS-DOS and derivative versions (Int 2 1h and AH=09h)$, or at the end of file editing in text editing programs, before, vi and derivative versions, so: $ matches lines or strings, Grep. $ is used to define string variables in the old version of BASIC programming language ($ "is usually used here as the pronunciation" string "instead of" dollar "). $ is used to define hexadecimal constants in languages like Pascal (such as Delphi) and some variant assembly languages. $ is used to define variables in PHP programming language and scalar variables in Perl programming language (see Sigil (computer programming)). In AutoIt automation, a procedural language is necessary, in which any variable has a $ at the beginning of its name. In most movie scripting languages written by shell, $ is used to insert special variables of environment variables, perform arithmetic calculations and characteristics, and translate localized strings. In UNIX-like systems, $ usually depends on the user's shell and environment settings as part of the instruction prompt. For example, the default environment is set to strike as part of the command prompt, and the shell specifies $. A language for TeX typesetting, used to divide mathematical areas. Use the $ prompt command DOS to insert a special sequence in the DOS command prompt string. Microsoft Excel is the convention, and other reports use $ to indicate absolute reference to cells.
