古今中外，许多人致力于圆周率的研究与计算。为了计算出圆周率的越来越好的近似值，一代代的数学家为这个神秘的数贡献了无数的时间与心血。十九世纪前，圆周率的计算进展相当缓慢，十九世纪后，计算圆周率的世界纪录频频创新。整个十九世纪，可以说是圆周率的手工计算量最大的世纪。-ancient times, many people committed to the ratio of the circumference research and calculation. In order to calculate the ratio of the circumference increasingly good approximation, the generations of mathematicians for the mysterious few of the numerous contributions of time and effort. Before the 19th century, the ratio of the circumference calculated Progress has been very slow and 19th centuries, we have calculated the ratio of the circumference of World Records frequently innovation. Throughout the 19th century, it is the ratio of circumference to the manual calculation of the largest in the century.
