Apparently, 39 decimal places is enough for most calculations in the universe, something to do with the width of a hydrogen atom.
They almost changed Pi to 3.2
3.2 is approximate value of pi which Babylonian and Egyptian used around 4000 years ago 
Is there also a pie.delivery API? 
Personally, I prefer Archimedes' method, using exhaustion. Here's a link to it because I'm too exasperated to type out the whole thing by hand :/
Vedas are claimed to provide clues to deep scientific concepts hidden within them.
In Rig Veda(oldest known Vedic Sanskrit Text), the value of pi upto 32 decimals is written in form of sloka.
this depends on your location...

this process also works asynchronously... you send a pie request and probably some time later a guy will knock on your door with your pie... enjoy...

I love Numberphile. Even if i often don't understand anything 
Here is mine 
Most smartest of all.
Here are some math forumlas to calculate pi. Give them a try.
Using Inverse Sine function (asin) - take any number x between -1 and 1 since the domain of inverse sin is [-1,1].
- 180 degree in radians is equal to PI
The App Inventor system "floats" all decimal places to 5 decimal places - 0.123456 would become 0.12345. So, I simply ran a JavaScript dialog, because Java(Script)'s Math.PI operator has 15 digits.
Just this:
alert (Math.PI);
Went online, found one million digits of pi.
Taken a large part from the website, if you are the author of the website, large thanks!
Made an AIA, tested successfully.

I do not know how many digits I took, seems to be thousands.
tasty... 
Very Nice Inforemations about Pi π here
Great to hear read...
if I scroll until end of that page, then my mouse would never work again I guess
Woah, an API for π nice
never imagined...
it probably costed him to host it , great guy though
Yeah, better and nice actually @Gordon_Lu
Sometimes I really like maths 
the actual full sentence was: I like maths only sometimes because I hate it a lot , btw, I can't make text even smaller as I wanted
I went on Google and found a list of URLs to images related to π and pie, and made a JSON list to put this together.
RandomPieImages.json (2.9 KB)
Together with this solution of calculating Pi, you can also use these to show a random pi(e) image.
