Arabic numerals are simple in strokes, easy to write, and easy to calculate by using decimal system, which has gradually become popular in various countries and become a universal number in the world.
The positions of Arabic numerals in Unicode encoding are 048 to 057.
Introduce to Europe
Ten numerical symbols were later introduced to Europe by Arabs, and were mistakenly called Arabic numerals by Europeans. Because the decimal method is used for counting, Arabic numerals are simple in strokes, convenient to write and clear in appearance, especially when used for written calculation, which is very convenient for calculation. Therefore, with the development of history, Arabic numerals have gradually become popular in various countries and become universal numbers in the world.
Into China
Around the 8th century AD, Indian numerals (Arabic numerals) were introduced into China with the spread of Buddhism, but they were not accepted by the writing system in China at that time. From about 13 to 14 century, Arabic numerals were brought to China by Muslims, but they were also unsuccessful. In the late Ming and early Qing Dynasties, China scholars began to translate a large number of western mathematical works, but all the Arabic numerals in the books were translated into chinese numerals. China first used Arabic numerals in the first year of Guangxu reign (1875), and imported Arabic numerals were introduced and used in the original version of mathematical writing. [2][3]
Matters needing attention
Arabic numerals can be easily changed by changing the position of the decimal point. Therefore, in special occasions (such as banks), it cannot completely replace capitalized Chinese characters and numbers.
Service rules
In sci-tech books and periodicals, Arabic numerals are frequently used because of their simple strokes, scientific structure, clear images and few groups. Whether their use is correct and standardized is directly related to the quality of sci-tech periodicals.
Where Arabic numerals are used.
The general principle of using Arabic numerals in sci-tech books and periodicals is: wherever it can be used, Arabic numerals should be used as long as it is suitable. [4] The main uses are:
(1) physical quantity. The numerical values of physical quantities must use Arabic numerals, and the units of measurement after the numerals must use legal units of measurement in China, such as 3 kg, 45 m, 2 min, etc.
(2) century, year, year, month, day and time. Such as: 1990s, 2005, 65438+February, 12, 16, 15, etc.
