Not sure where you’re going with the decimal thing. Pi had infinite digits in any base because it’s irrational.
Comment on suck it, math nerds
h3ndrik@feddit.de 8 months agoWas going to say the same. Also π isn’t infinite. Far from it. it’s not even bigger than 4. It’s representation in the decimal system is just so that it can’t be written there with a finite number of decimal places. But you could just write “π”. It’s short, concise and exact.

I thought that was the joke in the comic? That we can’t know numbers exactly that have an infinite decimal expansion. That’d be true for some rational numbers like a third, if you change the basis of the numeral system it’d be different numbers. And irrational numbers too if you have a integer base. But I’d argue how we write down a number isn’t what determines ‘exactness’.

Can pi be expressed with a finite amount of digits in another number system?

How about a pi based system, then pi is 1.

You’re correct.

Possible, but then the diameter would be an irrational number

I don’t think there’s any technical reason we can’t count in base pi

I’m pretty happy with being able to write integers in a finite number of digits. Wouldn’t want to give that up.

Well we need an integer base number system…

“A base is usually a whole number bigger than 1, although non-integer bases are also mathematically possible.”
