Apparently, 39 decimal places is enough for most calculations in the universe, something to do with the width of a hydrogen atom.

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 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...

Here are some math forumlas to calculate pi. Give them a try.

Here is the second Web API approach I found.

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!

I do not know how many digits I took, seems to be thousands.

Very Nice Inforemations about Pi π here

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.
