A quick way to show that a character is a genius is to have him recite pi to an absurd number of places. With its endless parade of decimal digits, π has both mystique and geek cred — it has its own holiday, it's splashed across mugs and T-shirts, calculating 1–10 millions of digits of π is a very common way of testing your CPU's power, and it's honored by movies and songs. Most of us never memorize it past a few places, so anyone who can fire off a hundred surely must be a genius, right?
For the record, odds are that your computer "knows" pi to the nearest multiple of 2^{-52}, about 2.168×10^{-15}, so about fifteen reliable digits. Ditto for e. You can compute it much more precisely, but you'll need to make your own storage.
The truth is, only a handful of digits are needed for most applications — only 11 decimal places are needed to calculate the circumference of the Earth to a millimeter,^{note } while only 42 are needed to find the circumference of a circle the size of the entire universe to within less than the diameter of a single proton. There's not much point in memorizing a hundred places other than to show off. (And indeed, after that many digits you can use whatever wrong digits you want because the math will still be pretty darn close — though you'll have a lot of mathematicians gritting their teeth…) For obvious reasons, this is a go-to Overly-Long Gag. For reference, here's a handy guide,◊ and another.
On the other hand, some people really do just enjoy the challenge of memorization, the same way a theater geek might memorize scenes from Shakespeare or a Trekker entire scenes from their favorite episode, and they do it for personal satisfaction rather than any desire to show up anyone else; any feelings of inadequacy are the responsibility of those who feel them, not the math geek's.
Perhaps the reason Reed Richards Is Useless is because he spends his time memorizing numbers he'll never use. It's also a common attribute of the Absent-Minded Professor and the TV Genius, as the contrast is a wonderful thing to show or rant about.
Inversely, a quick way to show that a character is stupid is to have him not know what pi is at all: "Apple or cherry?"

Examples:
- Sayonara, Zetsubou-Sensei had a kid recite the first few digits of pi...and get excessively hyped for this feat.
- Kyon of Haruhi Suzumiya supposes that the Intergrated Data Entity is smart enough that it "could calculate pi to the hundred millionth decimal point in just two seconds and do all sorts of advanced tricks."

- Subverted in a Fourth-Wall Mail Slot omake of Eyeshield 21, a reader asked how many digits of pi Hiruma can memorize. He replied, "3.14. If you need more than that, go check it from a book or something." The team mascot commented that he's the kind of guy who doesn't remember useless trivial stuffs.
- In Tantei Opera Milky Holmes, Queen Claris (as Sherlock) only needs to get as far as "3.14" to convince the others that she's not Sherlock.
- Ichika from Infinite Stratos recites Pi in his mind to force him to get his mind off the naked Charlotte who's changing right next to him after she dragged him into a changing room both to hide from some girls and to show him her outfit. It largely works as he enters a mantra and seems to be determined to recite the numbers.
- Manabe does this in episode 7 of Kotoura-san in an attempt to prevent Haruka from finding out what he may or may not be up to.
- In the manga Fate/EXTRA CCC Fox Tail, Saber/Suzuka Gozen starts bragging about her intelligence. Caster/Tamamo no Mae dares her to prove it by reciting the exact value of pi. Suzuka says she's not going to fall for that because pi has an infinite number of digits. Leo and Rani comment they have memorized pi to the 100th decimal, which shocks Hakuno.
- In Digimon Adventure: (2020), on episode 38, Joe Kido recites a bunch of things, including the first 41 digits of pi, to.....combat Mephistomon's mind control chant on some mook Digimon. Somehow, it works.

When it runs out of space, she starts writing them on paper and plastering them over her room before giving up.
- Discussed Trope in a The Cartoon History of the Universe footnote — the author believes that the accuracy of Pi is a pretty good indicator of a civilization's general mathematical/scientific ability. He then goes on to point out that The Bible specifies that the dimensions of the bronze basin for the Temple should be 10 cubits across, and 30 cubits around, putting the value of Pi at exactly three.
Solomon: And now you know why I hired outside contractors as the architects!
- Foxtrot:

- Another strip involved hiking the football on the count of pi. Naturally, they never got around to actually hiking the ball.
- In Monty, when Robotman disappears, he is replaced by an alien-human hybrid whose full name is 3.1415..., but his friends call him Mr Pi. Because the name was given to him as an insult he later changes it to Dave.
- A mostly forgotten character in Peanuts was 5, a kid whose family had numbers instead of names. In one strip where he appeared, Linus asked Charlie Brown what sort of name he'd like if that were the case with everyone:
Charlie Brown: How about 3.14159?Linus: I don't know, Charlie Brown... I have a feeling that every Tom, Dick, and Harry would be called 3.14159!
- In Pearls Before Swine, Goat tries to recite pi as a pickup line. It doesn't work.
- Mentioned as a subversion in Harry Potter and the Methods of Rationality, chapter nine, to lampshade Harry's broader intellect as compared to Hermione's Book Smarts. Harry knows pi down to six decimals because that's accurate enough for most practical purposes. Hermione knows a hundred decimals because that was what was printed in her math textbook.
- In Cowboy Bebop: Knockin' on Heaven's Door, Teen Genius Ed sings a little song that involves reciting pi. (With a few wrong numbers!)
- This is the motif of Darren Aronofsky's film π. The protagonist is a Mad Mathematician who seems to discover a 216-digit number that holds the Meaning of Life. In the climax of the film, he recites the numbers while having a breakdown. Ironically, the actual number pi appears nowhere in the movie except the opening credits. (The credits show pi to many decimal places, but only the first 8 digits after the decimal point are correct.)
- In Never Been Kissed, the Denominators put on a bake sale with a banner reading: "Pie = $1.00. Pi = 3.1457869986". Only the first two digits after that decimal point are correct, the rest is gibberish.
- In Night at the Museum: Battle of the Smithsonian Larry and Amelia have to solve a riddle to which the answer is Pi (something about the heart of the tomb of the pharaoh). They were helped by Bobblehead Einsteins, who proceed to tell them the (supposedly) correct combination. Larry constantly mixes them up, but Amelia remembers the numbers correctly. Apparently pi is less than ten digits long.
- In The Film of the Book Life of Pi, the title character writes it to a ludicrous length while introducing himself in elementary school. He does this to hopefully impress the kids enough so they would stop intentionally mispronouncing his actual name, Piscine, as "pissing". It works. From that day on, he's just "Pi".
- Thai exam cheating heist movie Bad Genius has one of the characters rattling off digits of Pi as establishing moment of his intelligence and rivalry with main character Lynn, another straight-A student.

- Discworld:
- The numbers-obsessed Mr. Bent from Making Money mentions that he'd mastered all the numbers except pi, but was working on it in his spare time and was sure it would give in sooner or later.
- Inverted in Moist's previous adventure, Going Postal. The Post Office's old sorting engine was designed by the infamous Bergholt Stuttley "Bloody Stupid" Johnson, who decided that pi was untidy, what with all that "never ending" nonsense, and therefore designed the crucial cog of the engine to have a pi that was exactly 3. This required or resulted in the machine containing a small part of the universe where pi does equal 3, causing some kind of rupture in space-time so that the machine started to spit out letters that hadn't been written yet, and then letters that would have gotten written if the writer hadn't written a different letter instead, and then letters that would never have been written in this particular leg of the Trousers of Time but were starting to bleed over from other legs because the engine was hurting for things to sort.
- In one of the books in Bryan Davis' Dragons in Our Midst series, part-dragon genius Ashley has to verbally calculate the square root of pi out to a certain number of digits as a passcode for her own (artificially intelligent, talking, almost-as-smart-as-her) computer.
- In the novel version of Carl Sagan's Contact it is discovered that at a particular distant point of the base 11 expression of pi a long sequence of 0 and 1's occurs that forms a bitmap of a circle. (Incidentally, pi is believed to be a normal number, which means that any sequence of numbers will eventually occur, with a frequency that corresponds to its random probability.)
- Cadaeic Cadenza, a pi mnemonic taken to 14 chapters and 3835 digits, containing "Pilish" imitations of The Raven, Hamlet, etc. And then the author went even further with Not A Wake, which encodes over ten thousand digits.

- Two characters in Douglas Coupland's Microserfs engage in what the narrator calls a "pi fight".
- The title character from Life of Pi earns his nickname by being able to recite over two whole blackboards worth of digits in front of the classroom. He did this because his full name is Piscine, which sounds a lot like "pissing", and he wanted to get a different nickname before his classmates made that connection.
- In one of the Time Warp Trio books, the main characters Logic Bomb a security robot that demands their ID numbers (which they don't have) by telling it that their numbers are three different irrational numbers, one of which is pi.

- The Doctor reels off the square root of pi to thirty decimal places^{note } in "Midnight". And the possessed woman who's copying everything he says recites it too. At the same time. Out of sync by several digits. By now everyone's realized that something is very wrong with the woman, but it's at this point when they start getting suspicious of the Doctor, too. Completely Played for Drama.

- The Hard N Phirm song linked above is really more a parody of this.
- Songs to Wear Pants To once wrote a song to serve as a mnemonic for the first 50 digits of pi. Just count the letters in each word:
Man, I can't — I shan't — formulate an anthem where the words comprise mnemonics, dreaded mnemonics for pi. The numerals just bother me always, even the dry anterior. Try to request something lower (zero) in numerary aptitude. Even I, pantaloon gallant, I cannot actualize the requested mnemonics, the leading fifty, I...

- In the Netrunner collectible card game there exists a card "PI in the 'Face"; its cover art includes a decimal expansion of the number Pi.
Like so many concepts of Netrunner, this card's design can be traced back to R. Talsorian's Cyberpunk 2.0.2.0. Roleplaying Game. Interestingly, in Cyberpunk, PI in the 'Face is not a defense program for data forts, but an attack program used by Runners to fry a data fort's CPU. [...] If the program makes a successful attack, the CPU will be trapped calculating Pi.
- One source in the Planescape campaign setting of Dungeons & Dragons mentions the moignos, creatures native to Mechanus (the Plane of Ultimate Law) that are obsessed with finding the finite value of Pi and spend every second of their existence trying to do so.
- The same source says that one easy way to confuse a modron (a far more common resident of Mechanus) is to ask it to define Pi. It will eventually give up, but trying to do so should distract it long enough for you to maybe get at something it's guarding or sneak something past it. (This usually only works on the less intelligent ones.)
- In Magic: The Gathering, Quandrix students take it one step further by reciting pi backwards.^{maths note }
- Moe the Clown does this in Phoenix Wright: Ace Attorney – Justice For All. It isn't to show intelligence, it's just one of his many puns.
- Minamimoto from The World Ends with You can not only recite Pi to 156 places but use it as a massive attack so strong that Crystal Dragon Jesus had to retreat to another universe. "Pi-Face" is also his nickname, and his HP from the two different times you fight are 3141 and 5926.

Max: You wanna write down the (phone) number?
Sam: Oh, I can remember the number. I wanna write myself a reminder to smother you with a pillow in your sleep. - Star Fox Zero: During the Area 3 mission, Fox has to leave behind his Arwing to control the Gyrowing, which is needed to control the reprogrammed Gigarilla superweapon.

46: 6. Damnit! - Variation in Homestuck: the Autoresponder doesn't show off just by reciting pi to an excessive number of digits, which isn't really all that impressive for a computer program, but by claiming to have calculated the final digit of pi (four). This is obviously impossible (pi is an irrational number that has no end) and he's only saying it to screw with Dirk, as Dirk rightly points out.
- Mike: Bookseller: "Lark to cash/wrap 3.141592653589."

Scott, a mathematician, reveals that he has memorised pi to 15,000 places; Duckula unwisely asks him about this and he starts demonstrating. Every time the scene cuts back to him for most of the remainder of the episode, he is still reciting. (At the end of the episode, he changes to reciting the largest known prime number, prompting Duckula to wail in despair.)
- The Batman episode "Q&A" involved the Cluemaster, a bitter ex-child genius hosting a deadly mock game show for the people he believes cheated them out of a win. Rules were simple- everyone gets one question, on any topic. They win and he lets them go free if they can ask him a question he doesn't know the answer to. One of them tries asking him the exact value of pi- he dismisses the question as being impossible to answer, but in the name of being a fair sport, he recites the first one hundred digits just to prove he's not weaseling out of it. Batman ruins the scheme by asking him "What is the true identity of the Batman?" Ironically, he is actually ''not'' a fair sport when he fails to answer, attempting to renege on the deal.
- Reversed in a Pinky and the Brain short on Animaniacs. Brain tells Pinky to ask him any question:

- In a special feature of the first Futurama movie, there is a math lecture and one of the topics is about pi. The lecturer asks the audience (that is, the Futurama staff which is chock full of math PhDs) how many digits of pi they know. Eventually, Matt Groening starts rattling off the correct digits...then some nonsense digits before ending with "333...and then just a whole bunch of 3's!"
- "Donald In Mathmagic Land" has a circular bird who recites digits of pi. And gets them wrong.
- In The Adventures of Jimmy Neutron, Boy Genius, Jimmy stops his Nanobots' second reign of terror by tricking them into deciphering the value of Pi. After a stressful read-through of all the digits, they seize up and overload on "five". He got the idea from seeing his Bumbling Dad with a lot of pie.
