- werdnapk 6y agoThat's not going to get you very far if you're looking for precision.
- netmare 6y agoThere's always 355/113. It's roughly approximate to 6.6 digits† and strangely it's been easier for me to remember than 22/7. † https://www.johndcook.com/blog/2018/05/22/best-approximations-for-pi/ https://www.johndcook.com/blog/2018/05/22/best-approximation...
- tombert 6y agoI like these kinds of things, but a part of me has always wondered why people don't want to just memorize it to six digits at that point. I mean, how long does it really take you to memorize 3.1415926? Or you could do what I always did, much to the annoyance of my high-school and college physics teachers, and just write down all my answers in terms of pi and never bother reducing it, since I would always argue that I can keep it exact that way :)

- sys_64738 6y agoYep 14th March and 22nd July are both PI Days. Who knew? :)
- analog31 6y agoOn my best slide rule, it's visibly just a tiny bit to the right of 3.14, but I doubt that I could guess a fourth digit very well if a similar number emerged from a calculation.
