gah more decimal!

What really gets me is when decimal is used when it would be just as clear to use hexadecimal. Like for instance, http://groups.google.com/groups?selm=451p8p$qcr@morgoth.sfu.ca&oe=UTF-8&output=gplain listing that the "40 billion'th binary digit of Pi is 1". How hard is it to say something like the 2^64th bit of Pi is 1/0?
