Editing 1292: Pi vs. Tau
Revision as of 17:21, 18 November 2013 by RainbowDash (talk | contribs) (→Explanation: The reference to 3+ digits is only single digits. The e+2 approximation is also unnecessary, because Randall states that 1.5pi can be conveniently written as e+2 but doesn't mention anything about its digits.)
