Ooooh, that's cool =]

Patrick · 2007-01-29 07:14:55

Or how about decimals of e and some irrational square roots?

power man · 2007-02-20 10:31:49

Toast i tried to get pi to a million places but my computer jammed up

mathsyperson · 2007-02-20 11:19:12

Here's a good way to compute pi:

For every term you put in that horrible-looking summation, the approximation gets around 100 million times more accurate, so it converges very quickly indeed. Unfortunately, the inclusion of factorials means that it still becomes very hard to compute once you get up to around the 10th term.

Jai Ganesh · 2007-02-20 16:16:01

Good method of finding the approximate value of pi, mathsyperson!
We know, pi is an irrational number, a transcendtal number,
whats the purpose of finding values of pi to greater degree of accuracy?
I think the value of pi, to 20 places after the decimal, would be sufficient!
The only other way it is used, probably, is genration or random numbers of hypermnesia tests!

Toast · 2007-02-20 19:09:04

Yeah I think remembering the values of pi, e, root 2, and phi to at least 20 decimal places is a great thing to do. It's a good way to get in touch with numbers and practice your memory skills.

Jai Ganesh · 2007-02-21 16:31:17

I do remember pi as
3.14159265358979323846264338327950288,
root 2 as 1.41421356236 and e as 2.7182818284.
I had memorized this long back (about 20 years ago!).

Anthony.R.Brown · 2007-03-21 01:41:50

I have a very Interesting Idea!

is it possible to convert pi to Computer code! represented by 1's and 0's

this may help to find a pattern!?

egeniius · 2007-03-21 02:16:06

Interesting indeed.

Anthony.R.Brown · 2007-03-21 02:50:14

Good Advert! egeniius!

have you found a Pattern!

A.R.B

egeniius · 2007-03-21 04:14:01

Yes! Nothing rational though ; 0 )

mathsyperson · 2007-03-21 04:28:16

I like how he got the first 2^16 digits of pi, wrote a code to convert them all into binary, then wrote another code to convert those binary digits into a sound, and at the end of all that the result was just a second of what you can get far more easily by detuning your TV.

His visual representation of pi looked kind of like what you get on a detuned TV screen as well.
So all in all, his efforts were a nearly complete waste.

Anthony.R.Brown · 2007-03-22 03:08:25

I have an Idea pi is a Circle! and eventually the two ends of the Circle will meet!
and when they do? the True Value for pi would have been found!
Maybe after some enormous Calculation the end joins the Start again!

luca-deltodesco · 2007-03-22 03:58:16

pi is not a rational number, it cannot be expressed with finite digits

Hey, um, give credit to me for actually finding that website.

Anthony.R.Brown · 2007-03-23 02:33:18

Does anyone know if pi has more Even! or more Odd! Numbers,or is it the same % Calculated so far!

Plus! the Zero's

PI?! What on Earth is Pi?!

hmmm cool is there any other ways to get pi??? 3.1415 for short
lmao and i like pie lol is there any others???

Isn't that Ramanujan's series?

As already addressed, yes, it is possible to convert it into any number based system. The lower the number, however, the more digits are needed to carry the same amount of accuracy. So converting it up to hexadecimal would be a better idea than converting it down to binary.

Hi javacodeman, and welcome to the forum! Feel free to start a thread about yourself in "Introductions"

John E. Franklin · 2007-04-12 04:56:45

Choco, Here is what pi is.

It's wintertime and you are at a perfectly round lake and it's great for skating.
One person skates straight across the lake through the middle to the other side.
And that is one kilometer or one mile, it's just an example.
Now then he skates along the edge of the lake back to where he started, which is
going around half a circle. Now he has gone 2.57 kilometers or miles all together because
3.141 divided by 2 is 1.57, so when he came back along the edge, he went 1.57 kilometers or miles.

So another person skates around the whole lake, she would go 3.141 kilometers or miles.
That's the number pi, about three, or 3.1, which is about 3% more than 3.
More accurately 3.141, which is about 5% more than 3.

Also kilometers are shorter than miles by about 35%, but this example doesn't care how big the lake is, just the numbers, and how much bigger different numbers are.
