Does anyone know to how many places has PI been calculated?

Does anyone know if this task is still being persued?

IN excess of 33,000,000 places, as I recall, there are several different

algorithms that have been used. Most organizations that have been involved in

calulating pi, have given up through lack of interest and / or significant

return.

Send mail, if you want pointers to some of the more recent papers on

calculating pi. Actually, nothing significant has happened for a few years...

Actually, the Chudnovskys recently jumped into the pi game with a

Ramanujan-type formula, and beat Kanada in the race to 10^9 digits.

That's rather significant to anyone who knows anything about the field.

Of course it's still being pursued. The task of getting more and more digits

of pi has been pursued for thousands of years, with no sign of stopping.

What about memorising digits of pi? I know only about 400 digits. Any other

netters want to compete? :-)

Nope, its Federal Law. Calculating Pi is a very dangerous operaton. What if

some researcher discovers that Pi repeats after 100,000,000,000 digits? The

universe as we know it would then cease to exist. Congress was made aware of

this and passed a law prohibiting the calculation of Pi past ten million

digits. The only organization authorized to conduct research in this area

is a special branch of the Armys Doomsday Machine research operation. They

have machines designed so even if one discovers the answer that it will not

tell anyone about it.

I usually get myself a square dartboard two feet on a side and

inscribe a circle with a radius of one foot. Then, by throwing darts

at the board and counting the ratio of darts which are inside the

circle to darts which hit the board, I can easily calculate pi.

Of course, this technique is only usable by those who are as bad at

darts as your average random number generator. :-)

Not so, if you mean the "built-in" accuracy. Getting quite a few thousand

digits is no real problem. You do need good integer arithmetic algorithms.

Pi and the AGM: A Study in Analytic Number Theory and Computational

by Jonathan M. Borwein and Peter B. Borwein

Wiley-Interscience, 1987

The AGM in the article is the arithmetic-geometric mean iteration

method of Gauss, Lagrange and Legendre.

From the book:

First recorded attempt to calculate Pi was 2000 BC

As of July 1986 (just prior to publication) Kanada had calculated

2**25 decimal digits of Pi using an algorithm that is described in the book.

I assume his later results use a modification of the same algorithm.

Useful if you need to keep everything in integers, but otherwise you

might as well just learn 3.141593. If you ever need more precision,

it'll be easier to extend that knowledge to get 3.1415926536 than it

This may be silly, but I learned to memorise the first few digits

of PI in high school by the nice pattern they made on the keyboard of my

SR-10 calculator:

7 8 9

/

4 5 6

| / /

1 2 3

0 .

You have to remember the "3." youself, but after that, it's up from

the 1, then diagonal from the 1, then diagonal from the 2. On the other

hand, e doesn't make such a nice pattern (that I noticed), so as far as I

remember, e is just 2.something.

I dunno - the numeric pad pattern for e isn't that bad:

7 8 9

4 5 6

1 2 3

0

Now: e = 2.7182817, approximately.

2, diagonally to 7, drop to 1, diagonally to 8,

drop to 2, directly to 8, back to 1, and directly to 7.

The multiple precision algorithms may be sophisticated, but they

are there in Knuth's The Art of Computer Programming.

You can find some interesting early work on the calculation of

large numbers by browsing through Scripta Mathematica from the

days of Jekuthiel Ginsberg's editorship. It carried reports of

work on rotary mechanical calculators generating the first 17

Mersenne numbers, for example. Someone helped that gentleman

calculate two numbers whose product is the 18th, or something

near it, on one of those electronic doodads.

I found Scripta Mathematica interesting recreational reading until

Ginsberg died. When his backlog was used up it became another

of those journals that carry papers that only ten people in the

world can read. The good issues are from the 1950s and early '60s.

e is 2 . 1828 1828 45 90 45 ...

That's the part that has the simple mnemonic structure. You have to

memorize something to remember more.

As undergraduates, a couple of us computed e to 9845 decimals. That was

the amount that would fit twice into the 20000 digits of the IBM 1620

we did it on while leaving room for the add table and the program.

We told Professor Mielke what we had done and he showed us a nice fresh

paper in Mathematical Tables and Other Aids to Computation, by someone

at the David Taylor Model Basin (whose name I've been trying to remember

since this thread began) about the calculation of pi to 100,000 decimals.

A footnote offhandedly announced that they had also calculated e to the

same precision "by the obvious algorithm". I have a nice letter from

him and a reprint of the MTOC paper. And a listing of our results which

confirmed his first ten thousand places.

The `at' doesn't belong. So much for that mnemonic. Oh, well, there are

many more where that came from. See Bergmann's book. I know a few that

even he doesn't list (though I don't use them myself).

The longest one I've seen is in Chinese. It's a poem (if you can call it that)

in which each character sounds like the corresponding digit in the decimal

expansion. (The decimal point is included.) Unfortunately, I don't remember

where I saw this. Could someone send me a reference? (A pointer to a Chinese

Well, 40115 of the little devils would do it... Actually,

that would give accuracy to about 1 part in 10^8.

Sort of like the time a friend was bar hopping years ago, here

in Silicon Valley. He ran into this girl who worked in mark-and-pack

at the end of the assembly line at a local I.C. manufacturer. They

talked a while, maybe even on a coule of nights, and she told him

that she could "get him any I.C.s he wanted", right off the line.

Well, "Hell!" he says; why not. Tells her he could use whatever

7400s she could get. (Yeah this *was* a while back!) Couple weeks

later, he runs into her again and she says that she has something

in the car for him. Yep. About 2000 Seventy Four Zero Zeroes...

Now, isn't there a theorem that proves that you can build ANY logic

One. Cut out a strip of paper of width twice the length of the resistor,

draw a line down the middle,.... :-)

First, it's "three point one four ONE five nine" ("two six five three...").

Your knowledge of poetry, if not of pi, should've told you that.

Second, I hope no one mistakenly supposes that the lengths of the words in

that limerick represent the first few digits of pi. `[F]avorite' spoils it.

Third, setting it at three is a foolish idea which has been tried many times

throughout history. (Some have even tried to set it at four!)

I screwed up... yes, there should be a "one" there... also, in

checking the original, "value" in the first line should read

"project"... apologies to all...

It's a joke. Please DO NOT take it seriously.

Special to Scott: I *like* the anti-socialist propoganda in

"A History of Pi". :-)

Ludolph van Ceulen spent much time calculating pi to 35 (?) decimal places.

He also wrote a verse (in Latin) for remembering the first 32.

Unfortunately I have forgotten how it went ... :-)

I kinda like the following myself:

How I need a drink! Alcoholic, of course, after all

night studying quantum mechanics!

Counting the letters in each word, you get:
