Hi, to put it in formal terms - this is how the format An is defined (with Xn, Yn being the length and width of an An paper:
X0 * Y0 = 1 m^2 (normalization of the base) Xn+1 = Yn (elegant recursion) Yn+1 = Xn/2 This yields two interesting features: 1) Xn * Yn = 1 m^2 / 2^n 2) Xn / Yn = sqrt(2) 1) establishes a straightforward relation with the metric system. 2) provides the best known irrational number in a measurable way. ;-) cheers oliver -- Linux-UTF8: i18n of Linux on all levels Archive: http://mail.nl.linux.org/linux-utf8/
