Abu'l-Hasan al-Uqlidisi

From Wikipedia, the free encyclopedia

Abu'l Hasan Ahmad ibn Ibrahim Al-Uqlidisi was an Arab mathematician, possibly from Damascus. He wrote the earliest surviving book on the positional use of the Hindu-Arabic numerals, around 952. It is especially notable for its treatment of decimal fractions, and that it showed how to carry out calculations without deletions.
