Value of pi Pi is an irrational number, which means that it is a real number that cannot be expressed by a simple fraction. ... When starting off in math, students are introduced to pi as a value of 3.14 or 3.14159. Though it is an irrational number, some use rational expressions to estimate pi, like 22/7 of 333/106.

The crux of the argument is that pi is a ratio comparing a circle's circumference with its diameter, which is not a quantity mathematicians generally care about. ... Tau is precisely the number that connects a circumference to that quantity. But usage of pi extends far beyond the geometry of circles.
