Indian mathematicians invented the concept of zero and developed the Arabic numerals and system of place-value notation used in most parts of the world today better source needed.The term often implies a decimal number written using these digits, which is the most common system for the symbolic representation of numbers in the world today, and is also called HinduArabic numerals.
However the term can mean the digits themselves, such as in the statement octal numbers are written using Arabic numerals. It was in the North African city of Bejaia that the Italian scholar Fibonacci first encountered the numerals; his work was crucial in making them known throughout Europe. European trade, books, and colonialism helped popularize the adoption of Arabic numerals around the world. The numerals have found worldwide use significantly beyond the contemporary spread of the Latin alphabet, intruding into the writing systems in regions where other variants of the HinduArabic numerals had been in use, such as Chinese and Japanese writing. The Oxford English Dictionary uses lowercase Arabic numerals to refer to these digits, and capitalized Arabic Numerals to refer to the Eastern digits. Prior to Brahmagupta, zero was in use in various forms but was regarded as a blank spot ( sunya sthana ) in a positional number. It was only used by mathematicians ( ganakas people doing calculations) while the general populace used the traditional Brahmi numerals. After 700, the decimal numbers with zero replaced the Brahmi numerals. The system was revolutionary by limiting the number of individual digits to ten. It is considered an important milestone in the development of mathematics. Their work was principally responsible for the diffusion of the Indian system of numeration in the Middle East and the West. The decimal point notation was introduced by Sind ibn Ali, who also wrote the earliest treatise on Arabic numerals. Al-Nasawi wrote in the early eleventh century that the mathematicians had not agreed on the form of numerals, but most of them had agreed to train themselves with the forms now known as Eastern Arabic numerals. The oldest specimens of the written numerals available from Egypt in 873874 show three forms of the numeral 2 and two forms of the numeral 3, and these variations indicate the divergence between what later became known as the Eastern Arabic numerals and the (Western) Arabic numerals. Al-Uqlidisi then invented a system of calculations with ink and paper without board and erasing ( bi-ghayr takht wa-l maw bal bi-dawt wa-qirs ). The use of the dust board appears to have introduced a divergence in terminology as well: whereas the Hindu reckoning was called isb al-hind in the east, it was called isb al-ghubr in the west (literally, calculation with dust). The numerals themselves were referred to in the west as ashkl alghubr (dust figures, in Ibn al-Ysamin) or qalam al-ghubr (dust letters). The divergence in the terminology has led some scholars to propose that the Western Arabic numerals had a separate origin in the so-called ghubr numerals but the available evidence indicates no separate origin. At this time, knowledge of the numerals was still widely seen as esoteric, and Talhoffer presents them with the Hebrew alphabet and astrology. He was known to have requested mathematical treatises concerning the astrolabe from Lupitus of Barcelona after he had returned to France. There, when I had been introduced to the art of the Indians nine symbols through remarkable teaching, knowledge of the art very soon pleased me above all else and I came to understand it. See G.F. Hill, The Development of Arabic Numerals in Europe for more examples.) In central Europe, the King of Hungary Ladislaus the Posthumous, started the use of Arabic numerals, which appear for the first time in a royal document of 1456. By the mid-16th century, they were in common use in most of Europe. Roman numerals remained in use mostly for the notation of anno Domini years, and for numbers on clockfaces. The system was used in Russia as late as the early 18th century when Peter the Great replaced it with Arabic numerals. In the early 17th century, European-style Arabic numerals were introduced by Spanish and Portuguese Jesuits. Masking to the lower 4 binary bits (or taking the last hexadecimal digit) gives the value of the digit, a great help in converting text to numbers on early computers. These positions were inherited in Unicode. EBCDIC used different values, but also had the lower 4 bits equal to the digit value. Cengage Learning. ISBN 1439084742.
