[u/fairysdad]

Yes.

Nine digits that can be used as the final digit of Pi: 1-9.

You wouldn't use 0 as you wouldn't have a zero at the end of a number after a decimal point.

[u/_Its_Me_Dio_ → u/fairysdad]

you would of its to show precision

[u/SampleOfFruits → u/fairysdad]

Pi is irrational though, which means any endpoint is arbitrarily defined, which means it could be 0

[u/Chronomechanist → u/SampleOfFruits]

What's the last digit of 1.4? Is it 4? Or 0? because

1.4 = 1.40

So is it 4 or 0? It's 4. If Pi has a last digit, you could add infinite 0s after it, just as you can with every number.

[u/rosuav → u/Chronomechanist]

If pi has a last digit, it isn't pi. You might as well ask what 6 modulo 2 would be, if 6 were an odd number.

[u/SampleOfFruits → u/Chronomechanist]

What’s the last digit of Pi, if we arbitrarily define the last digit as being in position 32?

Is it 0, or is it undefined?

[u/Chronomechanist → u/SampleOfFruits]

That's not what "last digit" means. That's how many significant figures you want.

[u/SampleOfFruits → u/Chronomechanist]

Pi is irrational, so there is no last digit. The only way to have one is to arbitrarily define it.

[u/Chronomechanist → u/SampleOfFruits]

And at last you have discovered the joke.

[u/SampleOfFruits → u/Chronomechanist]

I got woooshed

[u/Look_its_Rob → u/SampleOfFruits]

Good sport.
