@Empshok, currently taking numerical analysis in my last semester of college and fearing for my life that I might not pass and graduate. *cries mathematically*

@Jaune Arc, pi is a transcendental number. Look it up, it's interesting as fvck if you're into that sort of thing. You are 100% right though, the fractions are approximations that are close to, but not pi

TIL 40 digits of pi is enough to calculate the size of the observable universe with an error the size of less than a molecule. (Assuming that the observable universe is a sphere)

No. This is wrong. I didn't learn Taylor Series for shjt like this.
