I learnt that on pi day :)

Pi is infinite.
Pi is not infinite. It has infinitely many digits. It's like saying you are numerous because you have numerous hair on your head.

none because I am too clever to memorize it everybody will cry

22/7 should be enough.

The error is 0.04%!

If you can calculate powers, factorials, and square roots in your head, you can "remember" as many digits of pi as you want :)

Though for all practical purposes, "slightly more than three" is more than sufficient :-)

(I can't even remember all my passwords...)

Well, such formulae exists in maths but they are seriously tedious to calculate and nearly impossible in mind.
There is so much hype around it but so accuarate with many digits of pi are never used anywhere.
Best approximate ratio is 355/113 which is used in some fields. After all, 22/7 and 3.14 are the most common worldwide.

I remember 3.1415926

I just do everything with 22/7, it's our first time learning about pi, and we have textbook excersises where they say take pi as 22/7 and take pi as 3.14, I always do 22/7 tho..

It actually is. No one uses so many accurate digits of pi anywhere.
