A little mathematics joke on PI day (3/14/2024)
You must log in or register to comment.
I’m not 100% sure what the last digit of pi is, but I’ve narrowed it down to 10 numbers.
If you express pi in binary you can narrow it down to just two!
Arguably, 0 can’t be the last digit since you can leave it out without changing the value of a number. So the last digit is 1.

meaning it’s an even number

I’d guess that the last digit is 2. Please feel free to prove me wrong
Your guess is “the last digit is 2”. This necessarily implies that your full guess is: “there exists a last digit, and that last digit is 2”. I’ll happily prove that wrong :)
PI does get irrational sometimes. It do be what it is.
Same here. I’m not always rational myself. I don’t have the moral high ground to judge π in any meaningful way
I would bet my left achilles tendon that its a 9. The vibe it gives off is odd number-ish
I like symmetry, so I’m hoping it’s a 3
The last digit of pi is clearly the i, which would be equivalent to 19 after converting to base 10.
How is i equivalent to 19? It’s that a typo and you mean 9?
“i” should be 18 if we’re extending hexadecimal to enneadecimal.
Yeah, i get that pi is a very od number and two is like the most even number
Don’t do it, buddy! They may look like the last digits of Pi because of all those zeroes that follow, but it’s just a really long string of zeroes that starts up with random digits again after a while!
What’s wrong with me, why am I getting so annoyed that the other comments are acting like there’s actually a chance it’s right? Are they just being funny, or do they actually think the question “what’s the last digit of pi” makes sense? Even if they’re wrong, why should I care?!
They’re just being silly, man. That’s literally the joke.
What is wrong with you is that you’re not realizing that your niche knowledge is not common knowledge.
It’s not common knowledge that the digits of pi go on forever?
(I think I’m asking this as a rhetorical question but I suppose I have to upgrade it to a genuine question)
It’s common knowledge, yes, but most people don’t care about differentiating between a humongously large number we are not capable of calculating vs an infinite number that can never be calculated even if we have a machine powerful enough to do it, because it’s not relevant to pretty much any day to day life.
iirc it can potentially make sense in the event that our universe turns out to be simulated and subject to floating point errors.
Nah, pi arises purely from math, it doesn’t depend on the universe. The number we call pi would still be an irrational number even if the universe is a simulation that uses a rational approximation of pi.
Happy Pi Day! Celebrate Circularity! Ride Bikes! Share Spherical Sonnets! Get around to doing things! Eat Round Food! 🍕🥧🔴🟠🟡🟢🔵🟣
There’s a 1 in 10 chance he’s right but also impossible to prove
Dope.
