# V. On the extension of the numerical value of π

@article{ShanksVOT, title={V. On the extension of the numerical value of $\pi$}, author={William Shanks}, journal={Proceedings of the Royal Society of London}, volume={21}, pages={318 - 319} }

In the ‘Messenger of Mathematics’ for Dec. 1872, J. W. L. Glaisher, Esq., has given some very interesting particulars regarding the calculation of π, in the justness of which the author generally concurs. He, however, differs from him as to the comparative merits of Van Ceulen, who, in the early part of the seventeenth century, calculated π to 36 decimals. Hutton’s formula also, given in the ‘ Messenger,’ appears, notwithstanding Hutton’s own opinion, to be not so well adapted for extensive…
