INTERSTING PI FACTS

*. Pi is an irrational number. It means that it cannot be written as the ratio of two integer numbers. 22/7 is a popular one used for Pi but it is only an approximation, which equals to 3.142857143...

*. Another characteristic of pi as an irrational number is the fact that it takes an infinite number of digits to give its exact value , i.e. you can never get to the end ofit.

*

. One of the most accurate fractions for Pi is 104348 / 33215. it is accurate to 0.00000001056%

*. First 100 digits
