I think you mean "numerals" (or just "numbers"). 😅😬

sudoMakeUser@sh.itjust.works · 40 pts · 76d (1 reply)

Digits would work best

OrteilGenou@lemmy.world · 23 pts · 76d

That's what she said. sigh

ccunning@lemmy.world · 16 pts · 76d

Thanks - I was so confused before you cleared it up for me

Zulu@lemmy.world · 7 pts · 76d

No no, they're on to something. No repeating decimals too!

silver_wings_of_morning@feddit.dk · 47 pts · 76d (2 replies)

There are no decimals in the serial number, therefore there are also no repeating decimals

sudoMakeUser@sh.itjust.works · 3 pts · 76d (1 reply)

Every whole number has infinite repeating decimals of zero, kinda.

Sunsofold@lemmings.world · 3 pts · 76d

They're implied, kinda.

Now do your credit card.

LodeMike@lemmy.today · 4 pts · 76d (11 replies)

It's not possible because that's 16 digits.

Ziglin@lemmy.world · 6 pts · 76d (9 replies)

Base 16 would like a word.

LodeMike@lemmy.today · 6 pts · 76d (7 replies)

Credit card numbers are in base 10

Ziglin@lemmy.world · 2 pts · 76d

Seems to be correct, I was thinking of a different card in my wallet.

Ahem I mean I fancypants McGee have the 16 element identity permutation for my card number!

kkj@lemmy.dbzer0.com · 1 pts · 76d (3 replies)

Everything is in base 10 (unless it's in unary).

general_kitten@sopuli.xyz · 2 pts · 76d (1 reply)

not if i debase your currency >:3

Gonzako@lemmy.world · 1 pts · 70d

I'd personally enjoy it if it was you doing the debasing

LodeMike@lemmy.today · 1 pts · 76d

Base ten then

mangaskahn@lemmy.world · 1 pts · 75d (1 reply)

What if they are generated in base 16, but numbers containing a-f are discarded. Did you think about that? Huh?

LodeMike@lemmy.today · 1 pts · 75d

Yes. The check digit is calculated using base 10

badlilbean@sh.itjust.works · 5 pts · 76d

Please tell me base 16 isn't trying to hex-a-decimal

RogueBanana@piefed.zip · 4 pts · 75d

Let me be the judge of that. Maybe you missed it, let me verify it for you.

Bluegrass_Addict@lemmy.ca · 16 pts · 76d

hey neat! I have that exact same bill!

mavu@discuss.tchncs.de · 10 pts · 76d (4 replies)

fun fact: 1$ bill weighs almost exactly 1 gram and you idiots don't even use the metric system.

whambawhomp@lemmy.world · 16 pts · 76d

Fun fact, all US customary units are defined in terms of the metric system. For example, 1 inch is exactly 2.54cm. which means a US mile is 1.609344km. Americans have be using a bastardized version of the metric system since 1959.

It actually changes based on how much cocaine and human fluids it absorbs. That sounds like a joke, but I used to calibrate currency scales. There would be one setting for regular bills, and one for crisp, brand new ones; those would weigh measurably less and required compensation.

affiliate@lemmy.world · 4 pts · 76d

We might consider it if you updated the definition so that 1 gram was exactly the weight of a US dollar

ThePrimitive@lemmy.world · 3 pts · 76d

A nickel is 5 grams and you don't use the metric system either.

Now that's an interesting firing order.

None of this 1-8-7-2-6-5-4-3 or 1-8-4-3-6-5-7-2 nonsense, no

Just 8-4-3-1-6-7-2-5 👌

magnetosphere@fedia.io · 10 pts · 76d

I can’t help but wonder how you noticed this

panda_abyss@lemmy.ca · 7 pts · 76d

This is very satisfying

I heard somewhere recently that the length of a USD One Dollar bill is the average human penis length

Town@lemmy.zip · 7 pts · 76d (1 reply)

US bills are 6.14 inches (156 mm) wide, which is significantly larger than the average US penis size (5.16 inches).

https://www.science.org/content/article/how-big-average-penis

A 6.3 inch erect penis is larger than 95% of men.

OrteilGenou@lemmy.world · 4 pts · 76d

Well okay, but the average width is still 2.61 inches, surely

Pretty sure that's the 5 euro note mate.

Valmond@lemmy.dbzer0.com · 4 pts · 76d (4 replies)

Someone figure out the probability!

BeanGoblin@lemmy.blahaj.zone · 13 pts · 76d (3 replies)

If I remember high school math correctly, The first digit can be anything so, 10/10 options, the second digit cant be be the first so only 9/10 options, then 8/10 for the third, continue this pattern for each digit and multiply together you get 1.8% chance.

bigbangdangler@reddthat.com · 5 pts · 76d (2 replies)

10 x 9 x 8... etc. yields 1,814,400 possible combinations of no repeats, right? I'm confused what the "whole" is if this is expressed as a percent.

kkj@lemmy.dbzer0.com · 6 pts · 76d (1 reply)

100 000 000, the number of possible serial numbers.

bigbangdangler@reddthat.com · 4 pts · 76d

Aha, that makes sense. Thanks.

BarneyPiccolo@lemmy.today · 3 pts · 76d (2 replies)

A lot of people collect bills with interesting serial numbers, with stars, etc. a serial number with all the same numbers, or in numerical order, a palindrome, etc., all carry premiums.

This is an intriguing one. It would probably be interesting to them, because it doesn't have any repeating numbers, but it isn't obvious, like if they were in order. Still, I'll bet it's worth a little more than $1, but not much.

Biffsbraincell@lemmy.zip · 2 pts · 75d (1 reply)

Somebody might, but as a group they don't value these. They are pretty picky, there's a lot of notes of there.

The type closest to this would be Ladders I think. Like 12345678 or 23456789. True ladder are very rare and valuable but broken ladders are pretty common. By the time you get to something like 67890432 you probably wouldn't have any premium to the average buyer

BarneyPiccolo@lemmy.today · 1 pts · 73d

Yeah, that's what I figured. It's mildly interesting, but mildly doesn't translate to $.

Approximately 10987654*3/10^8 so about 0.0018144 I think?

kerrigan778@lemmy.blahaj.zone · 1 pts · 76d

A sequential bill

You might be able to get more than a dollar for it from a collector. There are numismatists that like interesting serial numbers. Probably won't get a lot since they aren't in order but who knows.
