Pi Approximation

[Yamaeda]

I just saw a funny meme about a fraction that approximated PI to 2600 digits. That got me thinking of trying to find some, and this was my result!

22/7 (the real PI day) is surprisingly good at such a simple fraction. 355/113 is a really good approximation and you need to get to 99733/31746 to get the best 5 digit one. With the last one it's correct to 10 digits!

What we really need is a TAU day...

More PI for everyone!

Cool!

Hey, this is 2026, so why not use a map instead of variant attributes?

On a side note, you could gain about 10-20% by just replacing the format into decimal string with a typecast. 😄

One flaw is that the third and fourth item have the same ratio
