Eastern Arabic numerals the medieval-era Iranian mathematician and engineer Khwarazmi, whose name was Latinized as "Algoritmi". These numbers are known as ("Indian numbers") in Arabic. They are sometimes also called "Indic numerals" in English. However, that is sometimes discouraged as it can lead to confusion with Indian numerals, used in Brahmic scripts of India. Each numeral in the Persian variant has a different Unicode point even if it looks identical to the Eastern Arabic numeral counterpart. However the variants used with Urdu, Sindhi, and other South Asian languages are not encoded separately from the Persian variants. See U+0660 through U+0669 and U+06F0 through
History of the Hindu–Arabic numeral system History of the Hindu–Arabic numeral system The Hindu–Arabic numeral system is a decimal place-value numeral system that uses a zero glyph as in "205". Its glyphs are descended from the Indian Brahmi numerals. The full system emerged by the 8th to 9th centuries, and is first described in Al-Khwarizmi's "On the Calculation with Hindu Numerals" (ca. 825), and Al-Kindi's four-volume work "On the Use of the Indian Numerals" (ca. 830). Today the name "Hindu–Arabic numerals" is usually used. Historians trace modern numerals in most languages to the Brahmi numerals, which were in use around the middle of the 3rd century
