what hindu author is credited with the development of the decimal system
Hindu–Arabic numeral system The Hinduâ€“Arabic numeral system[1] (also called the Arabic numeral system or Hindu numeral system)[2][note 1] is a positional decimal numeral system that is the most common system for the symbolic representation of numbers in the world. It was an ancient Indian numeral system which was re-introduced in the book On the Calculation with Hindu Numerals written by the medieval-era Iranian mathematician and engineer al-Khwarizmi, whose name was latinized as Algoritmi.[note 2][3] The system later spread to medieval Europe by the High Middle Ages.
