It has lots of crazy properties that really intrigued the ancient Greeks who studied it. The main one is that it is irrational. This means that it cannot be written as a finite or a repeating decimal. (The normal way that is taught is that it cannot be written as the ratio of two numbers). It is approximately equal to 3.14159 Hope that helps. -Doctor Ethan, The Geometry Forum
