5	Whenever math gets involved with the story things can get complicated, the resident mathematician will crunch the numbers and assert their solution is foolproof. Inevitably, the claim comes crashing down, sometimes literally, and the mathematician will make a gesture of embarrassment and say, "I must have misplaced a decimal point."
6
7	This comes as an analysis of complex systems and the inherent flaws of trying to develop an equation for anything and everything in the real world. It could also just be a humanizing flaw, where the math should have been perfect but they didn't account for all variables due to ego, naivete or arrogance. It can also be done deliberately, see also UsefulNotes/HollywoodAccounting.
8
9	In real life actual decimal mistakes are unlikely, since among mathematicians and scientists decimal notation is usually not the easiest way to write something. More common are radicals, fractions proper and improper, constants (such as pi or the natural base), and scientific notation.[[note]]Though technically, using the wrong exponent here is equivalent to misplacing the decimal point, sometimes over many orders of magnitude.[[/note]] It does, however, happen at times--not very often (as traditionally one keeps track of things in terms of integer multiples of the lowest common currency, such as integers of cents instead of decimals of dollars)--in finance. It was an occupational hazard for engineers and scientists in the days of slide rules -- see the Real Life section for details.
10
11	The most likely cause of the prevalence of this near iconic catchphrase for a mathematics error is a combination of WritersCannotDoMath and EverybodyHatesMathematics. Misplacing decimal points is a characteristic of elementary school and middle school arithmetic. Thus, this will most commonly show up in works aimed at children, for the reasons that it doesn't take much for a kid to consider a term as advanced mathematics and that the writers themselves, being kids at heart, are the writers least likely to have taken advanced mathematics.

13	Subtrope of EEqualsMCHammer. Compare with CarryTheOne, the other arithmetic mistake common in fiction. See also {{Mismeasurement}}. TwentyPercentMoreAwesome is when this gets applied to more abstract ideas.

24	* ''Manga/GreatTeacherOnizuka'': Urumi says this to her math tutor when he thinks he's solved a ridiculously complex equation she posed to him. She says if he solves it within five minutes, she'll give him her panties.

27	[[folder:Comic Books]]
28	* In ''ComicBook/FantasticFour'' comics, Victor Von Doom misplaced a decimal when planning a clandestine scientific experiment. When his roomate Reed Richards tried to point it out to him, Doom went into a rage at the suggestion that he could have made a mistake and went ahead anyway. The experiment literally blew up in his face, scarring and forever embittering him against Richards, convinced that [[NeverMyFault he must have changed the calculations in an attempt to sabotage him]].
29	* In the ''ComicBook/LuckyLuke'' episode ''Outlaw'', the Daltons (the original ones, not the cousins from the later stories) try to divide their loot among themselves. Having had no actual schooling, they [[EpicFail fail horribly, turning a simple long division into a mathematical nightmare]]. Bob Dalton uses his gun to place a decimal point "to simplify things".
30	* At the end of ''ComicBook/SupermanRedSon'' [[spoiler:Luthor's plan to destroy Superman and TakeOverTheWorld seems to have succeeded without a hitch... only for it to be revealed that Superman is still alive due to Luthor having misplaced a decimal point when he calculated Supes' density. However, due to Luthor having made Superman see the error of his ways as well as the world being a better place under Luthor's rule, he decides to let Luthor think he won and live the rest of his days in anonymity.]]
31	* Superman, as seen in the page image for WritersCannotDoMath, thinks 20 times 16 times 10 equals 32,000 (the correct answer is 3,200).
32	* In ''ComicBook/TheFlintstones'', local scientist [[Creator/CarlSagan Dr. Carl Sargon]] (uh, NoCelebritiesWereHarmed, thank you) calculates the trajectory of an asteroid with an abacus, concluding that it will collide with Earth in just a few days, destroying everything and killing everyone. [[spoiler: The calculations were wrong because a couple of moths had been breeding in the abacus, and Sargon took them for a bead.]]
33	* ''ComicBook/TheUltimates'': Banner considered that Captain America would barely have enough strength to talk. He awakes in full force and proceeds to trash the floor with everyone. Banner admits that must have misplaced a decimal point somewhere.

37	* PlayedForLaughs in a strip of ''ComicStrip/PearlsBeforeSwine'', where Rat ([[NewJobAsThePlotDemands currently working as a waiter]]) takes advantage of a couple trying to figure out the right tip by recommending them to take the price of their meal and move the decimal one space to the ''right''.

43	* In ''WesternAnimation/{{Sing}}'', the prize for the talent show was intended to be $1000 (composed mostly of various junk stuffed in a chest), but due to some antics with a GlassEye, the secretary in charge of writing the ads ends up typing $100000, which attracts far more performers than usual and causes various other problems.

47	* Invoked in all versions of ''Film/TheProducers''. When begging Leo to not report his small scale embezzlement at the beginning, Max tells him he should just misplace a few decimals.
48	* The given cause of the plan's failure in ''Film/OfficeSpace'' was that Michael misplaced a decimal point, which results in far too much money being siphoned off. He claims that he always makes similar minor mistakes.
49	** More justified than most examples due to the simple fact that Michael wasn't doing math, he was writing a computer program that involved math. It's much easier to make a mistake like this under such conditions.
50	* Muppet movies:
51	** In ''Film/TheMuppetMovie'', Kermit tries to buy a car at a [[HonestJohnsDealership rather disreputable dealership]], but can't afford any of them, until Sweetums swats a fly, which creates a decimal point in a price tag; the dealer finds himself selling a $1195 car for $11.95, after paying a $12 trade-in on the Muppets' [[TheAllegedCar old lemon]].
52	** At the end of the telethon in ''Film/TheMuppets2011'', the titular characters have raised $9,999,999 - one dollar short of the $10 million they need to save their theater. As Richman gloats, Fozzie bangs his head against the money counter in despair. The display flickers, rolls, and resets... revealing that the decimal point wasn't displaying correctly, and that they actually raised only $99,999.99.
53	* ''Film/KellysHeroes'' uses this as a throwaway gag when [[TheScrounger Crapgame]] calculates the value of the NaziGold that [[TheHero Kelly]] is trying to steal. He initially comes up with $1.6 million, but two scenes later announces that he misplaced a decimal and it's actually $16 million.
54	* In ''Film/KillMeAgain'', the broke private eye played by Val Kilmer desperately needs some dough to get out of town. He checks his bank balance by phone and is agreeably surprised to find he has $732, then crestfallen to learn that the clerk meant $7.32.
55	* In Creator/JamesBelushi vehicle ''Film/MadeMen'', Belushi plays Bill Menucci, a ConMan who stole twelve million dollars from the mob he worked for ''just'' before he [[TheStoolPigeon became a witness for the Feds]] and was placed in witness protection. During the film his old mob, a group of local criminals, and [[DirtyCop the crooked]] local sheriff who's secretly having an affair with Bill's wife Debra all come after him for revenge, the money, or both. When the sheriff catches up with Bill and Debra he's especially pissed, because he and Debra were planning to steal the money from Bill, except Debra told him Bill had only taken $120,000. Bill finds that ''hilarious'' and teases Debra about leaving out zeroes and misplacing decimal places... [[MoodWhiplash right up until the sheriff abruptly shoots her in the head]]. That kind of sucks the humor right out of the situation.

58	[[folder:Literature]]
59	* In one of the ''Literature/HaroldShea'' stories by Creator/LSpragueDeCamp and Fletcher Pratt, where magic has a mathematical basis, one of the characters has to prove his magical skills by invoking a dragon. The guy accidentally shifts the decimal point two places to the right and summons 100 dragons. Luckily they're vegetarian.
60	** A later attempt to perfect the spell produces a dragon approximately 0.01 times the size of a normal dragon. It's ten inches long, breathes fire, has a sting in its tail...and was summoned into a cage made for the normal-sized dragon the characters were hoping to get. It promptly escapes by flying '''between''' the bars...and it's not happy.
61	*** It is, however, ''adorable''.
62	* In ''Literature/UnseenAcademicals'' , the Bursar of Unseen University is said to regard the decimal point as a nuisance. Inevitably, this leads to Ponder Stibbons taking over his responsibilities. Although being utterly mad may have more to do with it (not that that stopped him before) as he had previously been shown to be very mathematically adept.
63	** As of ''Literature/TheScienceOfDiscworld'', the Bursar is now ''too'' mathematically adept to bother with decimal points, or real numbers. "Of course, he was a natural mathematician, and one thing a natural mathematician wants is to get away from actual damn sums as quickly as possible and slide into those bright sunny uplands where everything is explained by letters in a foreign alphabet".
64	** It might be noted that the bursar of a university is in charge of the ''finances''. Not exactly a position for someone who can't be bothered with decimal points (or someone who is barking mad, if it comes to that).
65	* In ''The Purchase of the North Pole'' by Creator/JulesVerne, the antagonists' plan is doomed to fail from the very beginning, because, as it is revealed in the end, the mathematician responsible for it was interrupted while writing down Earth's perimeter, which caused him to effectively move the decimal point three places to the left.
66	* In "Homo Sol", a short story by Creator/IsaacAsimov, an alien scientist mentions an occasion when one of his students thought he'd disproved a longstanding theorem. It turned out he'd misplaced a decimal point ''in an exponent'', meaning his result was 10,000,000,000 (10^10) times too large.
67	* In the ''Franchise/StarWars'' [[Franchise/StarWarsExpandedUniverse Expanded Universe]] ''X-Wing: Mercy Kill,'' main character Voort saBinring is a genius mathematician using his skill for strategy and tactics both in starship combat and in commando situations. He develops one of these vaudevillian schemes to capture the villain (of course, the reader is not told the details because otherwise [[UnspokenPlanGuarantee the scheme would fail]]) but when executing it, he decides he had "missed a variable" when they kidnapped a person who was supposed to be kidnapped by other people to attract attention.
68	* In ''Literature/TheSack'', Senator Horrigan does this twice, first when he multiplies 100,000 by 120, then when he multiplies 100,000 by 180. He gets 120 and 180 million, respectively.

72	* In the ''Series/MysteryScienceTheater3000'' episode "[[Recap/MysteryScienceTheater3000S08E06TheUndead The Undead]]", Tom Servo misses a single question on the tests given to the cast by the Brain Guys (which everyone else fails horrendously but Gypsy, and it's suggested via OverlyNarrowSuperlative that she'd have failed if they'd been able to decide on a control set) for this reason.
73	* ''Series/RedDwarf'':
74	** The episode "[[Recap/RedDwarfSeasonIIQueeg Queeg]]" features a hologram named [[DrillSergeantNasty Queeg]] [[spoiler:(actually Holly pulling a prank on the crew)]] who insults Holly's IQ in this manner.
75	--->'''Queeg:''' It has a six in it, but it's not six thousand.\
76	'''Lister:''' Well what is it?\
77	'''Queeg:''' [[DeadpanSnarker Six]].
78	** Played with in the episode "[[Recap/RedDwarfSeasonIVWhiteHole White Hole]]". Holly's IQ has been significantly increased (to 12,000) in exchange for [[ExplosiveOverclocking exponentially reducing her lifespan]]. When looking at her new lifespan, the screen displays 345 before she realizes "The decimal point, where's the decimal point?" She then discovers that she has 3.41 minutes left to live.
79	* In the ''Series/DoctorWho'' episode "[[Recap/DoctorWhoS36E7ThePyramidAtTheEndOfTheWorld The Pyramid at the End of the World]]", a misplaced decimal point during a biochemical experiment results in a highly voracious bacteria that threatens to wipe out all life on Earth within a year, if it gets out into the atmosphere. Why was it misplaced? Because one of the scientists accidentally broke her reading glasses, and her colleague had a bad hangover.
80	* In the ''Series/WKRPInCincinnati'' episode "The Contest Nobody Could Win", Johnny Fever misreads the prize for a radio contest as $5,000 instead of $50.
81	* ''Series/TheWire'': When Major Colvin is at COMSTAT presenting his official report that illustrates a 14% drop in felonies in the Western District as a result of his Hamsterdam project, Bill Rawls is skeptical of Colvin's numbers and says he's going to have them looked over to make sure Colvin didn't leave out a decimal point between the 1 and the 4.
82	* ''Series/ThePartridgeFamily'': In "Forgive Us Our Debits," Shirley buys a $29 cuckoo clock and receives a bill for $290 thanks to a computer glitch. When she goes back to the store to get it fixed, repo men show up at the house threatening to take her furniture if she doesn't pay the $2900 she owes.
83	* ''Series/TheBigBangTheory'': In the episode "The Romance Resonance", Sheldon theorizes a new element, only to discover that he has made a horrible mistake.
84	-->'''Sheldon:''' The table. It's in square centimeters. I read it as square meters. Do you know what that means?\
85	'''Amy:''' That Americans can't handle the metric system?
86	* In the ''Series/{{NCIS}}'' episode "Trapped", Nick Torres accidentially makes a 5,000 dollar donation to a charity instead of the 50 dollar donation he meant to make. [[spoiler:At the episode's end, when he meets up with the person in charge of the charity to fix the mistake, [[Heartwarming/{{NCIS}} he sees how much the accessible playground built by the charity means to disabled children and tells said person that there wasn't a mistake.]]]]

90	* Bentley sometimes steers you directly into security in ''VideoGame/SlyCooper'' because of this or CarryTheOne. As a rule, [[IfMyCalculationsAreCorrect if he says his calculations are correct]], [[TemptingFate he's wrong]].
91	* Plato's ten-fold error, mentioned below in RealLife, shows up as a plot point in ''VideoGame/IndianaJonesAndTheFateOfAtlantis'', both in regards to the distances Plato gave, [[spoiler:as well as the number of {{Orichalcum}} beads required to make the Atlantean [[UpgradeArtifact ascension device]] work properly.]]
92	* In the early days of ''VideoGame/CityOfHeroes'', the smoke bomb in the /devices powerset reduced foes' perception to zero, allowing /devices blasters to kill foes with impunity. This turned out to be due to a misplaced decimal in the magnitude of the debuff (50% instead of 5%), and was subsequently corrected.
93	* Discussed in ''The Answer'' of ''VideoGame/{{Persona 3}}''. When speculating about why the researchers were wrong in predicting that [[spoiler:the destruction of Tartarus would also cause the Abyss of Time to cease to be, and that said Abyss would have no Shadows]], Junpei makes the following retort:
94	-->'''Junpei:''' Did they forget a decimal place or somethin'?
95	* ''VideoGame/TouhouFuujinrokuMountainOfFaith'' has a bug where Marisa Kirisame's lasers are ten times as powerful as they are supposed to be.

98	[[folder:Webcomics]]
99	* In ''Webcomic/QuestionableContent'', [[http://questionablecontent.net/view.php?comic=1458 Dora panics briefly because of one of these.]] Hannelore comforts her with that her CorruptCorporateExecutive mother made the same mistake, causing the Argentinian economy to collapse.
100	* In ''Webcomic/LeftoverSoup'', Max's older brother Mark died because [[http://leftoversoup.com/archive.php?num=358 he misplaced a decimal point during training and caused an accident.]]
101	* In ''Webcomic/{{Melonpool}}'', technical guy Ralphie says he [[http://www.melonpool.com/?p=680 "must've missed a decimal point somewhere"]] during one of the time-travel paradox plots. It makes some sense in the context.

104	[[folder:Western Animation]]
105	* In ''WesternAnimation/EdEddNEddy'', Edd seems to have made this error on a few occasions.
106	* In ''WesternAnimation/TheAmazingWorldOfGumball'' episode "The Check", Louis gives the kids a check for $5000. Just as they are about to cash it at the end of the episode, Louis arrives and announces that he forgot to add the decimal point, making the check $50 instead.

109	[[folder:Real Life]]
110	* There's an urban legend that spinach is said to have a high iron content because once upon a time, someone misplaced the decimal point, and the figures on modern nutrition labels are because every single person in every nutritional agency in the world since is just making computations based on that figure, not doing tests of any kind. This is, of course, [[http://www5.in.tum.de/~huckle/Sutton_Spinach_Iron_and_Popeye_March_2010.pdf false]].
111	* Supposedly, the myth of Atlantis got started because Creator/{{Plato}} did the equivalent of misplacing a decimal point in his memoirs -- if he had recorded the east-west distance as exactly one-tenth of what he described, it would point directly to Crete. Decimals hadn't been invented then, but there was confusion about the meaning of a particular hieroglyphic, mistaking 100 for 1000.
112	* A Calorie is 1000 times as much energy as a calorie. [[http://en.wikipedia.org/wiki/Calorie That is, the "Calorie" seen in American nutrition charts is actually a kilocalorie.]] This has to rank among the stupidest units of measurement (i.e naming conventions) that exist. It seems deliberately designed to confuse and lead to errors.
113	** Creator/IsaacAsimov also mocked this concept in one of his scientific essays, and proceeded to use kilocalories (abbreviated kcal) for the remainder of his calculations.
114	** Which has led to the fallacy: "You need one calorie to heat up 1 g water (or another drink) one degree celsius. One liter of a softdrink equals roughly 1000 g, but contains less than 500 calories. So if you drink a cold softdrink, your body will burn more calories than the drink contains to heat it up to body temperature!" Unfortunately, the drink really contains less than 500'',000'' calories.
115	** Something similar can happen whenever someone mentions a "billion" of something. In the United States it means a thousand millions, in other countries it means a million millions (a thousand milliards). This is presumably one reason that Creator/StephenHawking used the word "million" in multiples throughout his book ''Literature/ABriefHistoryOfTime'' to describe large numbers. The British House of Commons actually passed a law in the 1970s to officially get rid of the (until then) common British term "milliard" because the City of London as a global center of finance could not risk milliards and billions getting mixed up.
116	* According to [[http://verizonmath.blogspot.com/2006/12/verizon-doesnt-know-dollars-from-cents.html this blog post]], Verizon in 2006 fell victim to bad unit conversion, advertising a data plan as 0.002 cents ($0.00002) per kilobyte but actually charging $0.002 ''in dollars''. They eventually refunded the blogger in question according to the advertised rate.
117	* There was an incident in Japan where something similar happened (an order to sell one share of a stock at 600,000 yen was instead entered as an order to sell 600,000 shares at one yen). A hikikomori who was watching the market reportedly caught the error and bought the shares in question, garnering a massive windfall.
118	* This was probably much more common in the past, as slide rules don't give you a decimal point except in a very limited range of calculations. You're expected to place it yourself from context. (It's how a simple sliding scale manages to be so versatile -- you make exactly the same motions to multiply something by 42, or 4.2, or 42,000.)
119	** It was common to accompany a complex accurate slide rule calculation with a 'back-of-the-envelope' recalculation. Use the slide rule to multiply 42.13 by 0.00972, and compare to multiplying 40 by 0.01 by hand as a check (except that a real calculation would likely have many more operations than a single multiplication.)
120	** This can happen nowadays as well if you use the [[http://en.wikipedia.org/wiki/Scientific_notation scientific notation]] and calculate the exponent separately. for example 7 × 10^5 times 3 × 10^7 can be simplified to 7 × 3 × 10^(5+7) or 21 × 10^12 adjusting the mantissa yields 2.1 × 10^13; forgetting to increment the exponent while adjusting will lead to the trope.
121	* In a brilliant aversion of StupidJetpackHitler German physicist Walther Bothe, who worked at their atomic bomb project, did exactly this when he determined the neutron free-flight length in graphite to be almost ten times smaller than it was in reality, forcing German nuclear project to use much more expensive and finicky heavy water instead of cheap and easily available graphite.
122	* A pilot on a flight from Maraba to Belem, on reading his flight plan, found his course was written as "0270". He interpreted it as 270 degrees (west), but in the flight plan it was assumed there was a decimal before the last digit, so the course was actually 027.0 degrees (roughly north-north-east). [[https://en.wikipedia.org/wiki/Varig_Flight_254 The plane ended up crashing in the jungle hundreds of miles from Belem when the fuel finally ran out. 13 people died.]]
123	* Some languages use decimal commas, so even a correct number can cause confusion to translators (compare 1,255 to 1.255).
124	* [[https://notalwaysright.com/someones-fingers-took-an-interesting-tumble/283396/ This]] Website/NotAlwaysRight story in which a customer calls in because a credit card purchase rang up for $1,852 rather than $18.52. Surprisingly, she's quite gracious about the whole thing, just politely asking them to fix the error but never raising her voice or trying to blame anyone.
