5 Million PI

[physic.dude]

In my seemingly infinite spare time, I have created what seems to be the only web page to host the first five million consecutive digits of Pi in one place.
(Warning: Loading times of 5-15 seconds are imminent. Browser crashes are possible. )

(Read Edit)

It's just a simple apache/ubuntu web server of mine. I probably wont keep it up for very long. :D

It was going to be to one BILLION digits, and I have the log file from the terminal session when I calculated it, but soon realized a 1GB text file is too hard to work with, let alone download from a server.


[U]Edit: Sorry, it got kinda boring, off line forever.

Here is the last few digits of 5 Million Pi from the 4,999,949th to 4,999,999th decimal places

You have too much spare time :rolleyes:

I was going to count them but i do not have much spare time as you. :D

That website crashed my browser. I hope your happy.

Sorry, I didn't mean it... :(

I've added a warning for the future.

[Rasa1111]

haha!

Almost crashed my FF to.
Well, Made it stutter for a few seconds anyway. lol

That's a lot of digits!
impressive. :P

oh yes.. and congrats! lol :)

p.s.. where did i put my car keys?

[m_duck]

Mmm, Pi...

[skierkyles]

Here's pie to 438,400 pixels.

Hmmm. Apple pie with clotted cream. I'm off to the kitchen.

<---- counted them and you have one too many! :popcorn:

<---- counted them and you have one too many! :popcorn:
That must be because the loop started at 0. :p:p
By the way, what did you use to calculate it?

A few cases of beer. :D

I used the the program 'pi'

sudo apt-get install pi

Hmm, lets check his manpage.

You probably just counted the file size (5000217 bytes).

Some of those bytes are from the HTML headers and formatting code.
1 byte is from from the point between 3 and 1.

There are actually only 4999999 decimal places. I suppose I should have said Pi to 5 million digits, not places.


Edit: I just changed all instances where I said 'places' to 'digits' on the site. :)

If you know how to script you can set something up that pulls down 1000 digits at a time, per each click.

Example:

00000000000000000000000000000000000000000000000000 00000000000000000000000000000000... Click for 1000 more digits (example.com)

For it to work seamlessly you need to set up what basically amounts to AJAX though. Either that or have Javascript calculate pi for you.

I guess so, but this is just a random site created out of boredom. I didn't build it to be a functional tool, but rather just a proof of concept.

I'm currently running it to 1 billion. 5 Million took me about 10 seconds, so I'm hoping a billion won't take TOO long, but eh. Gonna upload it to my blog for people to see. :popcorn:

Lol, good luck with that. I hope you have a task killing button on one of your panels.

Even if you do manage to get the entire thing on your blog, well, I'll let you figure that one out. :popcorn:

Terminal crashed on me so I booted into command line only mode. This time it worked, but I couldn't figure out how to save it as a .txt file. Any advice?

[Rasa1111]

can probably use the '>' command.

so, say you wanted to save the output of lspci..

lspci > listpcidevices.txtthis will "route" the output of lspci to a listpcidevices.txt file in the current (home by default) directory .
sorry if it wont help.

I remember when I calculated Pi to a billion places, use this command:

pi 1000000000 >file.txtIt will save the billion digits of Pi in a file named file.txt in your home folder.

In my seemingly infinite spare time,.....

LOL nice one. Sounds like something I would do in Javascript or PHP.

The question is; how do you know it is pi to 5 million dps? Why do you trust that program? Could it be just churning out digits at random?
A more interesting task is to set up an accuracy check. Calculate pi in at least two independent ways and compare for a few thousand dps.
This is a question for any large computational task, how do you know it is right?

[leviathan8]

Well, that was a nice workout for my browser. :P

Computers generally use pseudo ranom numbers. The generator only makes a lot of numbers, and when that "a lot" is reached, it usus the same list of numbers again. Therefore you would see repetition in cases of of 5 million numbers.

Its not random numbers, go to the following site and search for the last few digits from my calculation of Pi. (2076461971) Or any other position for that matter.

http://www.angio.net/pi/bigpi.cgi

You can also do it in reverse, have that site fetch 10 digits starting from the position of 4999990 and those will be the last 10 digits in my version.

Fail! The 531st place should be a 5, not a 7. ;)
