I am starting to think now that Pi has a billion digits (not infinite). The last number of Pi is 9.

Do you have a source?

This seems to indicate that it is a bit longer than 1 billion digits.

Do they also win an explanation as to how this applies to a thread about Pi? 😉

And with pi to 40dp you can find the radius of the universe to the diameter of a hydrogen atom, why know it to more?🙄

You don't have to win the explanation if you already know it, which enabled you to figure out the answer.

Duh.

😉

Think harder, and go google it.

I read somewhere that the numerical value of Pi is truncated to 50 decimal places.

 

[Doctor Q]

False. Pi's value cannot be displayed on a calculator.

You are correct! And that's the case even if you use this calculator, which I keep around for "e day". 😀

True.

Actually, it's false, but only because I was sneaky and said "she" even though Akira Haraguchi is a man. 😉

Let's try another one, and this time avoid the practical problem with the real-world calculator.

True or false? -

emw and I go to the zoo to see a newborn panda. It turns out that the one-day old panda has a head that is an absolutely perfect circle (from some particular direction, of course). We brought along a magic infinite-precision ruler/calculator. I measure the circumference to infinite precision. emw then measures the diameter to infinite precision. We press the divide key to divide the measured circumference by the measured diameter, again to infinite precision. Although we can't see the full result in the display, we've computed the exact value of pi.​

If the claim seems plausible, it might be because it's true. Or, since I admitted that I'm sneaky, there might be something subtle that's wrong with it. Or, I might be double-sneaky and I wanted you to waste your time looking for something sneaky. Or I could be triple-sneaky and pointing this out to confuse you! In any case, the question stands.

I am going to say false on this.

Just need to be sure to wear appropriate shirt for the day...

True, assuming the calculator calculates the answer correctly to infinite precision which along with having an infinitely precise ruler is impossible.

I'm guessing false, because I would guess a magic infinite-precision ruler/calculator probably wouldn't have keys because it's magic.

Smartass. 😀

Think harder, and go google it.

I'm just guessing here, but I think he was being sarcastic.

You are sneaky. 😛

Well, damn, if I knew the answer I'd be more than a happy man...

 

[WildCowboy]

Well, is the spooning courtesy of spicyapple, Katie Melua, or an MR member of my choosing?

I guess I'll go ahead and provide the explanation, since I already gave the answer. They're members whose member numbers correspond to successively more precise roundings of pi (ignoring the decimal point).

So:
Member #3 is Macrumors.
Member #31 (3.1) is outZider.
Member #314 (3.14) is an invalid user.
Member #3142 (3.142) is newterror.
And, member #31416 (3.1416) is Cobe.

We can't go all the way to member #314159 (3.14159) because we don't have that many members yet.

The chef at my local gastropub just gave me free Banoffee Pi 😀

 

[spicyapple]

I calculated 22/7 in Calculator and it gave me 3.1428571, so I thought the next logical member is lectroMAC. Damn you Calculator!?!

Ah well, so much for my knowledge of pi.

WCB, do you want your free spooning session with spicyapple at your place or mine? 😱

 

[Doctor Q]

OK, the answer to my Pi-themed Panda Puzzle is False. Yes, I was sneaky once again. The trick is the word "then", as in "emw then measures". Why? Because a one-day old Panda grows at a fast rate, so the panda's head will be just slightly bigger when emw then measures the diameter than when I measure the circumference! Even one more atom of panda will disrupt the calculation. Those pandas are such scamps!

OK, time for me to quit my pi-tiful attempts to make pi-uzzles, before you all stop being so hos-pi-table and run me off a preci-pi-ce! 😱

Well, actually, I'm preparing one more bit of geekitude for you, based on the digits in pi. It's a game/puzzle I made up for myself, but you might like to play too. It'll take me a little more work to write it up properly, so stay tuned. No need for tre-pi-dation!

This whole thread reminds me of Mole day in high school.

Ah...you fell for the trap that 22/7 is merely very close to pi. It's interesting that both of our methods yielded the same results (up until the final one that needed to be filled in).

We can go spoon in the Picture Gallery forum if that's okay with you...

You are very sneaky. How about this:
If you have the ultimate super calculator would infinite numbers multiplications would be truly accurate?
