Persian π Flag


Pi is considered a sacred number, what better way to have it stylized like modern Persia's flag.  In this case the number Pi is written in Arabic along the white stripes on the edges of the red and green stripes.  Likewise the central portion has the iconic symbol of Pi. 

National Greek π Flag



The national Greek π flag has 3 white stripes to represent three, 1 blue canton to represent 1/10th, and four blue stripes to represent 4/100ths of the number Pi, which equals 3.14.

Greek Numbers Pi Flag


Since the Greeks originally used letters to represent numbers, we have a flag that reads 3.14.  Gamma is the 3rd letter and is capitalized. Alpha is the middle letter which represents one, but it is lower case because it is a fraction.  Finally delta is the 4th number/letter.
