Emoticon numbers!

(related)

Your challenge is to output the highest number you can. You can output as a number or as a string. You must output something that matches the regex ^\d+$, as in only 0-9.

The Twist

Your source code must be:

  1. Same forwards and backwards

  2. 3 bytes long

  3. The middle byte must be different from the other two

Example valid:

0_0
)-)
m.m
xvx
W$W
@\@

Example invalid:

mnop
l__l
___
T_+
O_o
0_o

Snippets are allowed, you don't need a full program / function.

Highest number outputted wins!

1Why the downvotes? This was +2 in the sandbox – programmer5000 – 2017-06-08T21:48:35.247

3@programmer5000 Perhaps because its trivial, boring, and leaves little room for interesting solutions? I haven't voted on it, but this might be why it stands currently at +1/-4 – Conor O'Brien – 2017-06-08T21:49:44.683

6I downvoted because there are so few possible answers that it's impossible to be at all imaginative, and for most languages the optimal answer is the same (989, 9^9, 9e9, ...). – Doorknob – 2017-06-08T22:02:33.750

1"You must output something that matches the regex ^\d+$" - So e isn't allowed in the output at all? – Shaggy – 2017-06-08T22:40:57.000

1Quick, someone find a language in which 0/0 is Infinity. It's NaN in JS :/ – Stephen – 2017-06-09T17:58:50.257

@StephenS "You must output something that matches the regex ^\d+$" – programmer5000 – 2017-06-09T18:23:04.937

@programmer5000 Since snippets are allowed, does this mean that it could be assumed that the value returned is wrapped in a format call of some form - ie, could a snippet that outputs as 9000000000.0 or 9.00E+09 be assumed to return 9000000000? - (this would add 16+ languages onto my polyglot :P ) – Taylor Scott – 2017-06-13T04:08:46.233

@StephenS - I did it :P ; With 0/0 MATL takes input, implicitly convert to a numeric, and devides it by 0. This outputs Inf for all inputs which do not implicitly convert to 0. – Taylor Scott – 2017-06-13T17:25:13.220

Can someone tell me what J outputs for _ _? – Magic Octopus Urn – 2017-06-13T18:03:58.550

@carusocomputing I'm getting no output from that for particular string – Taylor Scott – 2017-06-14T13:30:16.580

I wonder what the lowest number would be... probably just 000 in most languages. – 12Me21 – 2018-03-03T15:49:26.473

How it works

ȷ denotes an scientific-notational number, as in 2ȷ6 for 2000000. Without digits on either side, it defaults to a value of 1000. * is exponentiation, giving 10001000.

I'm tempted to downvote this because it's pretty much an exact copy of programmer5000's answer, but since you don't have enough rep to see deleted things yet, I'll pass on calling you out for that. Have an upvote instead ;P – HyperNeutrino – 2017-06-09T00:03:04.083

@HyperNeutrino programmer5000's answer had been down voted and deleted for the reason he answered his own challenge with a trivial solution before even waiting for answers. I think posting another solution is pretty legitimate in such a case, I mean, someone had to post this. – Uriel – 2017-06-09T01:55:36.660

@Uriel Yes; I said I'd pass on saying it's a dupe partially because this is the obvious answer and because this answerer can't see that post in the first place. – HyperNeutrino – 2017-06-09T02:59:13.780

Found a bigger one thanks to ETHproductions informing me that strings were permitted.

LçL

Try it

Explanation

  • L is the Japt constant for the number 100.
  • The ç method, which takes string s as an argument, when applied to a number n, repeats s n times. If a number is passed as the argument, it's cast to a string.
  • So, reading LçL backwards, it's "100 repeated 100 times".

1You could also go for -.- which outputs the ASCII character code 255, and is also a relatively common emoticon. – Zack C. – 2017-06-09T18:39:35.880

@ZackC. I thought about it, but . will print ÿ where the question demands matching \d+. outputting through tape contents seemed to oversee this because it uses numbers (until printed). – Uriel – 2017-06-10T18:25:50.217

By assuming larger cells (I think 32-bit cell interpreters exist, possibly even 64-bit cells), you can get bigger values! – CalculatorFeline – 2017-06-11T17:00:36.910

@CalculatorFeline yea, but then I can claim for 1024, 2048, 4096... and there's no end (storage boundaries are not assumable). so I took on the common specs (and implementations) that lists 8 as a default when one exists. – Uriel – 2017-06-11T17:02:08.923

1"Languages are defined by their interpreters", so if you can find a 9999999999999999-bit interpreter, you can get 2^9999999999999999-1. – CalculatorFeline – 2017-06-11T17:03:39.350

@CalculatorFeline python's int are almost unbeatable, so surely an interpreter that uses the whole RAM for calculating this overflow design can come to trillions of bits. – Uriel – 2017-06-11T17:06:24.730

Python's integers are signed, so this would produce -1. You'd need an interpreter that wraps, finitizing the byte count. – CalculatorFeline – 2017-06-11T17:08:31.370

@CalculatorFeline I meant there could be an interpreter that tries to produce the highest possible number in case of overflow – Uriel – 2017-06-11T17:10:30.057

1I don't see why XeX would be cheating; 9e9 is the best possible answer in a number of languages, including JS. And even if scientific notation was cheating, this technically isn't using it, because e is actually a method here, multiplying the first number by 10 to the second ;-) – ETHproductions – 2018-01-13T00:48:18.377

QBIC, 10

?z?

The challenge specifically asks to "output" the number, and the only way to do that in QBIC is using ?. So this prints z (which is 10 in QBIC) followed by 2 newlines.

A slightly more relaxed take on the rules would give us this snippet:

z^z

which is good for 10,000,000,000. It doesn't output anything (in fact, it doesn't even assign the result), but as a 3-byte ABA snippet it reaches the highest number possible.

Since snippets are allowed,

may push 9^9 on the stack, depending on where in the code it is. An example of it working would be:

(the p merely prints, you could replace it with a nop and it would still work)
