Pi in base 8 is 3.1104… so it should be celebrated on March 11. Pi in hexadecimal is 3.243F… and should be celebrated on March 24.<br /><br />Pi Approximation Day is radix-independent because the approximation is based on integer division. It is celebrated on 22/7 (decimal), which is also 26/7 (octal) and 16/7 (hexadecimal), all of which yield the same approximate value of pi in their respective bases.<br /><br />It's a bit of a purist attitude. But I personally find July 22 a much more flexible and elegant approximation than March 14.<br /><br />That said, happy upcoming Pi Approximation Day 2010!Jamieson Christiannoreply@blogger.comtag:blogger.com,1999:blog-8916319.post-57706429331375115782009-07-24T15:14:50.423-05:002009-07-24T15:14:50.423-05:00Huh.
