It's a transcendental number (meaning not expressible as a fraction of two integers), in this case it's the decimal expansion, but I think it's simpler and more direct to think of it in terms of a formula, such as https://wikimedia.org/api/rest_v1/media/math/render/svg/33ad11b6609d91487577949c7a42872afdc33a36

The value produced is the universal ratio of a circle's circumference to its diameter (which maybe just as well could have been defined as the ratio of the circumference to the radius) in flat Euclidean space.

It's one of the most significant numbers in mathematics. it's central to so many different kinds of calculations.

Its 3.1

nothing, I'm all about that e to the power of τ/2 plus 1

I don't know her
