The German-Dutch mathematician Ludolph van Ceulen (circa 1600) computed the first 35 decimal places of π with a 2 62-gon. He was so proud of this accomplishment that he had them inscribed on his tombstone. [28]
Decimal places (world records in bold) All records from 1400 onwards are given as the number of correct decimal places. 1400: Madhava of Sangamagrama: Discovered the infinite power series expansion of π now known as the Leibniz formula for pi [13] 10: 1424: Jamshīd al-Kāshī [14] 16: 1573: Valentinus Otho: 355 ⁄ 113: 6 1579: François ...
Caldrini (1491) is the earliest printed example of long division, known as the Danda method in medieval Italy, [4] and it became more practical with the introduction of decimal notation for fractions by Pitiscus (1608). The specific algorithm in modern use was introduced by Henry Briggs c. 1600. [5]
