Summary

Description

English: Graph showing how the record precision of numerical approximations to pi, measured in decimal places (depicted on a logarithmic scale), evolved in human history. The time before 1400 is compressed. Based on data from w:en:Chronology_of_computation_of_π.

Esperanto: Grafeo kiu montras kiel la rekorda precizeco de ciferaj alproksimiĝoj al pi, mezurataj en dekumaj pozicioj (bildigataj laŭ logaritma skalo), evoluis dum la homa historio. La tempo antaŭ 1400 estas kunpremita. Bazita sur datumoj el w:en:Chronology_of_computation_of_π.

Deutsch: Graph, der die Entwicklung von immer besseren numerischen Annäherungen an Pi im Laufe der Menschheitsgeschichte anzeigt, gemessen in Dezimalstellen anhand einer logarithmischen Skala. Die Zeit vor 1400 ist verkürzt dargestellt. Basierend auf Daten aus w:en:Chronology_of_computation_of_π.

Português: Gráfico que mostra como o recorde da precisão das aproximações numéricas de pi, medidas em casas decimais (representadas em uma escala logarítmica), evoluiu na história da humanidade. O tempo antes de 1400 é compactado. Com base em dados de w:en:Chronology of computation of π.

Русский: График, показывающий, как развивалась рекордная точность числовых приближений к числу пи, указанная по количеству десятичных знаках (по оси ординат логарифмический масштаб). Время на оси до 1400 года н. э. сжато.

Derivative works of this file: Record pi approximations (vi).svg

This vector image was constructed using gnuplot and is based on the design of File:Rekordaj_alproksimighoj_al_pi.png by User:Marcoscramer. The gnuplot script below was used to design the image. Input file "pi.dat" consists of two white-space separated columns, the first containing year data and the latter the number of decimal digits.
