i think the “Purple Shirted Eye Stabber” is in about 3 comics.
1- himself
2- a nice man in blue then takes off his blue and reveals a purple and stabs a 5 – year old girl
3- green dude talking ( I think)
That’s definetly a fail.

Oh yeah!
Fractions are not inherently more accurate than decimals, except in cases where a number can only be accurately represented as a fraction.
PI is an irrational number. By definition an irrational number cannot be accurately expressed as a ratio or fraction.
355/113 is only accurate to 6 decimal places. The number that Alex gave you is accurate to several hundred decimal places.
Therefore, the fraction 355/113 is nowhere near as accurate as the decimal number Alex supplied. It doesn’t even come close. Hell, even my calculator gives a more accurate value of PI than 355/113 gives us.
So to sum up for the noobs known as pikorar and others tuning in.
Expressing 1/3 as 1/3 is more accurate than expressing it as 1.3333333
Expressing 1/8 as 0.125 is equally as accurate as using 1/8
pi = 3.1415926535897932 is more accurate than pi = 355/113
Expressing pi as 3+1/(6+9/(6+25/(6+49/(6+81/(6+121/(6+…)))))) is more accurate than either . . . indeed, it’s exact. (For computation out to umpty-ump digits, though, formulas like pi = 4(4·arctan(1/5) – arctan(1/239)) are frequently used.)
As far as I’m aware of, the original problem was that you shouldn’t round PI to 3, because that would be too inaccurate and would yield results for a hexagon (instead of circle). eg. radius * radius * 3 = area of a hexagon.
But just like any real number, PI can be rounded to any digits. The point being, don’t go too far.
It is also ‘no longer Pi’ if you do not round it… “1.23456 != 1.2345 != 1.2346″ Unless you are using the full Pi value to its however many billionth decimal place of course.
You HAVE to round Pi. It does not resolve. Even 3.1415926535 8979323846 2643383279 5028841971 6939937510 5820974944 5923078164 0628620899 8628034825 3421170679 is not the end of it…
That’s not even accurate. the first 5 decimels of Pi are 3.14159 and you cant say “ohm, they rounded the 9 into the 5 to make it 6″ because you cant round up after the decemel, also, Pi is not roundable.
Rounding Pi: 3.141593, Not rounding Pi 3.141592. With rounding, you are 0.0000004 above Pi, without it you are 0.0000006 below Pi. Rounding is more accurate in this case, but as others have mentioned you do not just round it directly to 1dp.
The whole ‘do not round Pi ever’ is nonsensical, it make calculations less accurate.
Anybody who took 4th grade math would know how to round. (Yes, I see the argument above about truncation v. rounding, and suggest that both are equally valid.) Also, anybody who took 1st grade English would know about capital letters and full stops. Anybody who took 2nd grade math would know they are called digits, not decimals.
yes, but then why dont they just do 3.14, as that is what is used (from 3rd grade math again) to find the circumference and area of a circle (yes i know it is used for more than that but that is the first use taught)
i’m not sure if i’m making this memory up or it comes from another area of maths, but when you write down Pi to however many decimal places you want/need shouldn’t you put a dot over the last digit to show that there are more decimal places but you are not showing them?
You all are missing the real fail. The sign should read “Speed limit: pi MPH”. There is no sense in giving a pure number as a speed. (actually, there is little sense in using that medieval unit system too. Why not using furlongs over dropfalls then?)
I’ve been trying to figure out if this is a real sign, too. I did some Googling and found a couple obviously ‘shopped “Speed Limit Pi” signs, but they look different from this one. I thought the starburst logo/emblem might have been the Smithsonian’s, but theirs looks slightly different. That’s all I got.
That’s rather irrational, dontcha think?
Makes sense if you want people to drive REALLY slowly around the block – especially if the “block” is a circle…
Or a pie :/
Mmmmm… pie is great.
Like warm apple pie.
It’s the American thing to do! I haven’t tried… is it great?
I think its perfectly rationa- oh, i get it…. jokes about πr^2 (pi are square, for you who are math illiterate)
aha! great!
*scritches head*
Now I want some Pocky!!
Pie aren’t square, cake are square.
Pie are around.
You failed understanding the math joke.
The root of this question is that we are just imaging it.
this makes no sense… seeing as the root of pie is not imaginary….
Is there a root of pi? without making rhubarb pie…
Unless this is a walking path, yes, that speed limit is very irrational. Should be at least 5π. Maybe they could have made it eπ.
Darn, that was supposed to be e^π. I guess this comment system doesn’t like the sup tag.
Sup wit you?
You have a creepy name…
Yes, because he’s clearly a purple quilted eye stabber.
The purple part I got, thanks. It’s the eye stabbing I’m worried about.
Maybe cyanide makes him happy.
If you ever saw a purple-shirted eye coming at you, would you freak out and stab it?

i think the “Purple Shirted Eye Stabber” is in about 3 comics.
1- himself
2- a nice man in blue then takes off his blue and reveals a purple and stabs a 5 – year old girl
3- green dude talking ( I think)
Or maybe they should’ve made it e^(i*pi)
-1 MPH? I don’t think so.
that wouldn’t be -1… try more like 2.71828182845904523^(3.1415…*i)
loooooool go take multivariable calculus and then get back to us
Hmmm, not quite. i is not -1; i^2 is -1.
seriously guys? don’t try to correct people on stuff you don’t know.
e*(i*pi) = -1
e^(ix) = cos x + i*sinx, when x = pi, that is -1
Or even transcendental…
Nice one!
Isn’t it a WIN ?
WINs are sometimes featured here; note that the word FAIL does not appear anywhere on the picture
It does, down in the very bottom-left corner!
Haha, you got him.
That’s definetly a fail.

Oh yeah!
Or if you want to be more accurate, it’s 355/113.
lmao you’re 355/133!!!
Yes, if by “more accurate”, you mean “less accurate.”
Actually, fractions are considered more accurate than a decimal. So.
What the fu are you talking about?
Something about which s/he knows not.
Fractions are not inherently more accurate than decimals, except in cases where a number can only be accurately represented as a fraction.
PI is an irrational number. By definition an irrational number cannot be accurately expressed as a ratio or fraction.
355/113 is only accurate to 6 decimal places. The number that Alex gave you is accurate to several hundred decimal places.
Therefore, the fraction 355/113 is nowhere near as accurate as the decimal number Alex supplied. It doesn’t even come close. Hell, even my calculator gives a more accurate value of PI than 355/113 gives us.
Owned.
So to sum up for the noobs known as pikorar and others tuning in.
Expressing 1/3 as 1/3 is more accurate than expressing it as 1.3333333
Expressing 1/8 as 0.125 is equally as accurate as using 1/8
pi = 3.1415926535897932 is more accurate than pi = 355/113
Expressing pi as 3+1/(6+9/(6+25/(6+49/(6+81/(6+121/(6+…)))))) is more accurate than either . . . indeed, it’s exact. (For computation out to umpty-ump digits, though, formulas like pi = 4(4·arctan(1/5) – arctan(1/239)) are frequently used.)
This is so fu**in definitely a WIN!!11!one!
it’s from oddly specific: failblog for signs or something like that.
Yes, I agree: It’s a win!!!
I think the title of the post is more of a win that the picture itself.
Aren’t all speed limits specific?
Yes, but not oddly specific.
Pi is 3.1415…not 16
It’s rounded from 3.14159
you owned him so hard
I always thought Megan was a girl’s name
You don’t round Pi. This was a fail.
I thought all pies were round. Oh, you meant … nevermind.
No, I’ve definitely seen pi squared.
and sometimes pi is hairy
Look; when your pie is hairy, just say good bye and throw it out.
or swoosh it around with a leaf blower!
And restrain it with a hair elastic
-shutters- ewwwwwwwwww
OK, let’s just zip down this lane at 3 miles per click and see what we can find for lunch. (where I’ll be soon)
i didnt even get lunch yesterday, i was too busy :\
No sofa time either?
Hey, complain to your union!
STRIKE! *jaymze walking solo in circles*
lol i am my own union… unfortunately i’m also my own management and management usually wins out.
No pictures!
nah, I happen to love a hairy mincemeat pie!
I disagree, PI r round! Cornbread r square!
You can’t disagree with facts; they’re not up for discussion.
Uh, yes, you round all numbers if you’re using a certain number of digits.
Maybe you’re just jealous because pi has a number and cupcake does not?
No, you don’t round Pi.
It is no longer Pi if you do.
As far as I’m aware of, the original problem was that you shouldn’t round PI to 3, because that would be too inaccurate and would yield results for a hexagon (instead of circle). eg. radius * radius * 3 = area of a hexagon.
But just like any real number, PI can be rounded to any digits. The point being, don’t go too far.
It is also ‘no longer Pi’ if you do not round it… “1.23456 != 1.2345 != 1.2346″ Unless you are using the full Pi value to its however many billionth decimal place of course.
It’s no longer pi if you truncate either. What is your point?
You HAVE to round Pi. It does not resolve. Even 3.1415926535 8979323846 2643383279 5028841971 6939937510 5820974944 5923078164 0628620899 8628034825 3421170679 is not the end of it…
i believe they mean you don’t round the last digit you use up or down, rather you simply cut it off and whatever digit you choose
Thank you. Was wondering if everyone here was an idiot.
Nope. Just most.
It’s also “not pi” if you truncate it, so it has the same issue regardless of whether you round up, down, or leave it alone.
Actually it’s apple.
That’s not even accurate. the first 5 decimels of Pi are 3.14159 and you cant say “ohm, they rounded the 9 into the 5 to make it 6″ because you cant round up after the decemel, also, Pi is not roundable.
What the fudge are you talking about?
I don’t trust the math skills of anyone who can’t use proper spelling and grammar.
Don’t forger about speedometer error (20-30%).
WIN! WIN!! WIN!!! I like this
FUN! FUN! FUN!
Mmmmmmmmmm peach chocolate pie…….
Sounds yummy.
you sound yummy.LOL

Christians are only allowed to drive at 3mph though.
Zing!
Total Win, no debate.
Yippee!
They should change it to ‘c’.
If that was a legal limit I bet Chuck Norris could drive faster.
Unless if Chuck Norris were a superior being living in the fourth dimension (which he isn’t), then no, he couldn’t.
I know that, but it was a joke, you nerd…
The fourth dimension lives in Chuck Norris
Rounding Pi: 3.141593, Not rounding Pi 3.141592. With rounding, you are 0.0000004 above Pi, without it you are 0.0000006 below Pi. Rounding is more accurate in this case, but as others have mentioned you do not just round it directly to 1dp.
The whole ‘do not round Pi ever’ is nonsensical, it make calculations less accurate.
that’s totally irrational!
anybody who took 3rd grade math would know pi’s first starting decimals are “3.1415″ not “3.1416″
Anybody who took 4th grade math would know how to round. (Yes, I see the argument above about truncation v. rounding, and suggest that both are equally valid.) Also, anybody who took 1st grade English would know about capital letters and full stops. Anybody who took 2nd grade math would know they are called digits, not decimals.
I can be pedantic too.
yes, but then why dont they just do 3.14, as that is what is used (from 3rd grade math again) to find the circumference and area of a circle (yes i know it is used for more than that but that is the first use taught)
Because “they” wanted to use more than 3 digits of precision in “their” calculation.
Should’ve just added ellipses:
pi=3.1415…
Or maybe the wavy equal sign to show approximation:
pi≈3.1415
So that would be 5 km/h then?
pi mph is nearly 5.05590329 kph. You can go waaaaaay faster than 5km/h.
That’s why there’s a speed limit.
the only fail is, that it’s speed limit instead pee limit
Caption Logic Fail: Why would you drive in circles if your top (linear) speed happens to be pi? Does not compute…
i’m not sure if i’m making this memory up or it comes from another area of maths, but when you write down Pi to however many decimal places you want/need shouldn’t you put a dot over the last digit to show that there are more decimal places but you are not showing them?
You’re thinking of recurring decimals, where the dot shows the digit sequence repeats from that point on.
i’m pisexual
You all are missing the real fail. The sign should read “Speed limit: pi MPH”. There is no sense in giving a pure number as a speed. (actually, there is little sense in using that medieval unit system too. Why not using furlongs over dropfalls then?)
anyone find where that sign is??
it is a big win.
I’ve been trying to figure out if this is a real sign, too. I did some Googling and found a couple obviously ‘shopped “Speed Limit Pi” signs, but they look different from this one. I thought the starburst logo/emblem might have been the Smithsonian’s, but theirs looks slightly different. That’s all I got.

This is a WIN!
what are u talking about? they rounded pi…
lol, yes how dare they
lol, they messed up pi. They said 3.1416 not 3.14159. (to be more exact, 3.14159265358 and so on)
pi = 3,14159265

pi is 3.1415 they did 3.1416
