Pi = 3.14159265359, or usually shorted to something like 3.14

Actually, pi is proven to just keep going forever with decimal digits. This pattern is also unrepetitive, or having no patern to it.

Or as Wikipedia says it, "It's [pi's] decimal representation never ends and never settles into a permanent repeating pattern. The digits appear to be randomly distributed although no proof of this has yet been discovered."

Pi is a ratio of a circle's circumference to it's diameter, as shown below.

This means that a circle's circumference is a little over 3 times as big as it's diameter.

This also means that you can write pi as pi = circumference/diameter:

Because of this, you will often use pi when your dealing with circles.

Thanks CPhill,

I actually learned some of this myself while looking at the wikipedia page.

I didn't know the whole circumference/diameter thing before reading it.

The picture is also from the wiki page :)

Thanks Ninja,

That wiki page is really good and copying the diagram into the forum was an excellent idea.

**I have added the address of this thread the sticky topic "Information Pages worth Keeping and Developing"**

---------------------------------------------------------------

Before this thread is closed I just want to make it very clear;

**pi is an irrational number.** This means that it cannot be exactly represented as a fraction and hence it it cannot be exactly represented by a terminating or a recurring fraction.

**ANY number value that is assigned to pi is an approximation.**

Pi is a number with many decimals, into the millions. Scientists en Mathematician almost discover these decimals like it's a sport. Here is the page with the most decimals on it i could found: http://newton.ex.ac.uk/research/qsystems/collabs/pi/pi6.txt .
