:: Which reminds me that I should work on a similar task for mean times. --[[User:Paddy3118|Paddy3118]] 06:55, 10 July 2012 (UTC)
:: It's not just a question of numerical stability, the real problem is that "average of directions" is a bad concept. "Mean" is inherently tied to summation, but summing directions is just ridiculous. What happens when you add east to north, do you get west, south, or north by northeast maybe?
:: Besides--it's moot--to get an angle out of a vector, atan(y/x) is no good: you need atan2(y, x). --[[User:Ledrug|Ledrug]] 07:42, 10 July 2012 (UTC)
