This is a very easy thing to memorize. The alternating series of the recipricals
of odd natural numbers is equal to pi/4. (that is to say 1-1/3+1/5-1/7...).
Cyclic numbers are rational numbers. While easier to predict the behaviour of,
they aren't (as a whole) more or less interesting or useful. Though, pi is
more useful than most rational numbers (with the possible exceptions of 0,1/2,1,2).

Eh? What are you talking about?
