Pi is the ratio of the circumference of a circle to its diameter. It is known to be irrational and its decimal expansion therefore does not terminate or repeat. The first 40 places are: 3.14159 26535 89793 23846 26433 83279 50288 41971...
There are few other numbers as small as 360 that have so many different factors. This makes the degree a very nice unit to divide the circle into an equal number of parts. 120 degrees is 1/3 of a circle, 90 degrees is 1/4, and so on. So while a deeg, being 1/100th of a circle, may seem nice and round to us ten-fingered folks, it isn't so convenient for dividing a pie into thirds.
