| contents | We study the square root computation by Leonardo Fibonacci (or Leonardo of Pisa) in his MSS Liber Abaci from c1202 and c1228 and De Practica Geometrie from c1220. We annotate a translation of Liber Abaci based on transcripts from 1857 and 2020 and a translation from 2002 and a transcription of De Practica Geometrie from 1862 and a translation from 2008. We show that Fibonacci is demonstrating the same method for all examples in the MSS and that this method deviates from the traditional description of the digit--by--digit method. The description of the method used by Fibonacci is all verbal and summarized in tables for each square root example. The manuscripts and transcription of the Latin texts are incomplete for some of the examples and the transcription and translation contains minor discrepancies and some of the tables are incomplete and the missing digits are inserted. |
