Summary edit

DescriptionRecord pi approximations (vi).svg	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.   W3C-validity not checked.
