He wrote the earliest surviving book on the positional use of the Arabic numerals, ''Kitab al-Fusul fi al-Hisab al-Hindi (The Arithemetics of Al-Uqlidisi)'' around 952.〔 The Arithemetics of Al-Uqlisidi, The story of Hindu-Arabic Arithematic, translated and annotated by A.S.Saidan, D.Reidel Publishing Company,Boston, 1978〕 It is especially notable for its treatment of decimal fractions, and that it showed how to carry out calculations without deletions. While the Persian mathematician Jamshīd al-Kāshī claimed to have discovered decimal fractions himself in the 15th century, J. Lennart Berggrenn notes that he was mistaken, as decimal fractions were first used five centuries before him by al-Uqlidisi as early as the 10th century. ==Notes== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Abu'l-Hasan al-Uqlidisi」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
