For anyone who doesn't know, pi (π) is a number that is always the circumference of a circle (the length of all the way around it) divided by its diameter ( how wide it is.), no matter the size of circle. it is approximately 3.14159265358979323 but continues forever. it is an irrational number, so it is impossible to have π updates in your inbox, as you can't have a fraction of an update in an inbox.
