Title: How much of pi do you know?
Post by: Groudon on September 29, 2006, 03:18:03 pm: The title means what is the value of pi that you know. I know pi up to 37 decimal places.

3.1415926535897932384626433832795028841

Up to how many decimal places do you know? I'll expect a lot of 3.14s in this topic, and not many others.

Post by: Groudon on September 29, 2006, 03:39:41 pm: Perhaps I should be more specific. How much of pi did you know before you read this topic?

Post by: KnucklesSonic8 on September 29, 2006, 03:43:16 pm: Before this topic, I knew and still only know 3.14.
ROTFLOL.

I hate Math so I don't dwell on things like that. :P

Post by: SadisticMystic on September 29, 2006, 04:10:12 pm: At my peak, I had 1011 digits (no, that's not binary for eleven). I've probably slipped back to about 500 by now since I haven't put it to any use in so long.

Post by: Bilan on September 29, 2006, 04:36:25 pm: before reading this topic: 3.142

Also SM wins.

Post by: Thorn on September 29, 2006, 04:55:59 pm: Before this topic, I knew 3.14159265358. But I still get away with using 22/7 in Calc BC class, so ah well.
Title: Re: How much of pi do you know?
Post by: yse on September 29, 2006, 08:40:42 pm: I should get my friend Ian to read this topic. He used to know it to about 600.

Unfortunately even 37 is beyond me, I know about 15.

3.14159265357989...
Title: Re: How much of pi do you know?
Post by: Groudon on September 29, 2006, 08:47:57 pm: And my friends in school were impressed at me knowing the first 37 decimal places. I had shown my one friend it, written down, and he told me to write it again, but on a different sheet of paper while he held the original. When I finished, he compared the papers, and called me a "genius" (they matched perfectly).

69399375105820974944
59230781640628620899
862803

So 86 decimal places. It's the most I've ever memorized, but I know it pretty well.

Well, it is binary for eleven, but I suppose saying 1011₁₀ would suffice. (But no subscript is just assumed decimal, since you didn't say 1011₂ or anything like that.)

I only know so far as 3.14159265358979323846264. I believe my brother is up to 46 or 50 or something.

Ha, beaten everyone by infinity.

Post by: General Throatstomper on September 30, 2006, 12:32:40 pm: Yeah, F-Man has us all beat.

I know very little pi. Before reading this topic, I knew 3.1415. But generally pi is approximated, and so it doesn't matter much. Unless a very precise answer is needed, such as in physics. In which case, 22/7 is a time saver. As is the 'Pi' button on a scientific/graphing calculator.

Though why commit (x) ammount of digits in pi to memory when you could always spend that time learning a new algorithim?

Title: Re: How much of pi do you know?
Post by: Marth on October 03, 2006, 07:38:38 pm: I was never told (in my schoolwork) to memorize more than the symbol π (duh), 3.14, or 22/7,
but I still knew 3.14159. I don't know how much I could memorize if I tried.
I know I could get a few more digits almost effortlessly (though there are more useful things
to memorize), and maybe I could surprise myself and memorize dozens or hundreds.
I don't think of myself as being really good with memory (except at memorizing a short thing
very quickly), but it seems easier to memorize stuff than I expect.

Title: Re: How much of pi do you know?
Post by: CosmicFalcon on October 08, 2006, 02:05:47 pm: Why is it always Pi? Why do people never discuss how many decimal points they know e to, or the golden ratio, or root 2? These irrational numbers are just as significant. Oh so you know one irrational number to lots of decimal places, good for you. It's hardly an achievement, what use does it serve? It's not like you'll use the actual value of Pi without a calculator, so you're hardly going to key in 389572957 digits when there's a Pi button.

Also, you fucking win for bringing up the Golden Ratio.

Just kidding, I already said it's pointless.

And you win for recognising its awesomeness.
