"Pi" and popular misconception.

The number π is a mathematical constant that is the ratio of a circle's circumference to its diameter. It has been represented by the Greek letter "π" since the mid-18th century, though it is also sometimes romanticized as "pi".


 \pi = \frac{C}{d}  


Being an irrational number, π cannot be expressed exactly as a ratio of any two integers (fractions such as 22/7 are commonly used to approximate π but no fraction can be its exact value).In fact, pi has been calculated to over two quadrillion decimal places and still there is no pattern. 

The value of pi to 100 significant figures is 
3.14159265358979323846264338327950288419716939937510582097 
4944592307816406286208998628034825342117067... 

The  value of pi up to 100,000 digits can be viewed on the site

There is also a movie  featuring  the pattern of pi whose trailer can be viewed  below.
