pi is an irrational number. This means that it continues forever and cannot be represented by a fraction. It is the number that you use to work out the circumference of a circle if you only have the diameter. There are two pi days; 14th of March (3.14 using the American format), or 22nd of July (22/7 using Australian format). The number pi is part of the Fourier Transform and Euler's Identity as well as many other important mathematical equations.
