### Pi in Binary

Pi in Binary

Take any circle, measure the length of its circumference then measure the length of its diameter and divide the two numbers. You get pi, probably the most famous number in all of mathematics and known for several thousand years.

pi=circumference/diameter

The decimal places go on forever and appear to be random.

But this is just one representation of the number, it's pi represented in base 10.

We can represent numbers in any base we please. In base 10 we have 10 symbols 0,1,2,3,...9 and in base n we have n symbols 0,1,2,3,...,(n-1)

The simplest base is base 2, because in that base we have only two symbols 0,1

Base 2 is also call "binary" and writing pi in base 2 makes it look like a computer data stream and even more mysterious. Here's pi in base 2..

What is this data stream encoding? Nobody knows.
