They laid out a spread at my office today, everything from meat pies to dessert pies, and, of course, pizza.

You know, I often see people abbreviate pi as 3.1415, but shouldn't it be 3.1416?

We are having our Pi Day party tomorrow [so technically, it's an =ROUNDUP(PI(),2) party for all of you Excel geeks]. My dearly beloved wife is scratch-baking 5 kinds of pie and one of the guests is bringing another. Should be a good time!

Pi to 4 digits should definitely be 3.1416. If they don't want to change digits to rounding, 3.14 or 3.14159 are good choices.

Are you trying to be rational about Pi.

Pi day is a fake holiday invented by math companies to sell more math.

Not necessarily! Is e + π transcendental? How about i?

My problem with imaginary numbers, how can one fail a test if the subject matter is imaginary?

e + π? Well, um, yes. Yes it is. i is not. (Or is it "i am not"?)

I missed the really good one, which was March 14, 2015, 9:26 and 54 seconds a.m. 3/14/15 9:26:54. Four years later and I'm still kicking myself over that one.

(I'm also still kicking myself for failing to throw a party on Feb. 29, 2000, because 2/29/00 is a date that comes around only every 400 years.)

Either $[​IMG]$ or $[​IMG]$ is transcendental, but the proof cannot reveal which one. Strange.

Some complex numbers are transcendental and some are not. If they can by used in a polynomial, they are not transcendental.

Not only is it PI DAY, it's also useless math BS day!

Pi has been calculated out to 31.4 trillion decimals, Google announces on Pi Day

On Thursday, Google revealed developer advocate Emma Haruka Iwao, with the help of the tech giant's cloud platform, calculated Pi to 31.4 trillion decimal places, beating the previous record by nearly 9 trillion digits.

To do this, Iwao's team used a program called ycruncher capable of computing Pi to trillions of digits powered by 25 virtual machines run through Google Cloud's Compute Engine.

"The biggest challenge with pi is that it requires a lot of storage and memory to calculate," said Iwao, who has worked with the company for nearly four years, in a blog posted published Thursday by Google.

The calculation required 170 terabytes of data, about the same amount of data as the entire Library of Congress print collection, said Google.
After about 4 months of calculating, Iwao arrived at the record-breaking result.
