The Nineteenth Byte

Mr. Xcoder

4:00 PM

@TuxCopter It does.

@Mayube Isn't it?

Mayube

no?

It's -0.7

Mr. Xcoder

yes?

TuxCopter

-1.7 should be -0.7 I think

Mr. Xcoder

No

TuxCopter

ninja'd

Mr. Xcoder

4:00 PM

@TuxCopter I don't think so

totallyhuman

it works for -3.5..?

it's probably just floating point bull

Mayube

yeah it'll work for 0.5 floats

Business Cat

@Mr.Xcoder Retina, 15 bytes

Mayube

but it'll fail for 3.4, 3.3, 3.6, 3.7 etc

Socratic Phoenix

wait... is the remainder after division by 1 always 0? What strange math am I missing here...

Mayube

4:01 PM

@SocraticPhoenix only for whole integers

officialaimm

@totallyhuman that is because it is giving off complements of decimal (0.3->0.7), 0.5 would remain same

totallyhuman

oh

Socratic Phoenix

@Mayube I still don't get it... 1.7/1 = 1.7... doesn't that have a remainder of zero?

totallyhuman

interesting

Mayube

@SocraticPhoenix no it has a remainder of 0.7

Mr. Xcoder

4:02 PM

@Mayube $(\forall x<0) frac(x)=x-\lceil x\rceil$

Mayube

1.7 / 1 = 1 r 0.7

Socratic Phoenix

@Mayube oh... I get it now..

officialaimm

Maybe this is because all the arithmetic calculation are binary number based under-the-hood...

TuxCopter

@Mr.Xcoder sed: s/[0-9]\+\./0./

I can't get \d to work

totallyhuman

@Mr.Xcoder \frac{num}{den} i think

Mr. Xcoder

4:04 PM

@totallyhuman Nope, frac is different than \frac. The latter is a fraction, the former is fractional part!

totallyhuman

$\frac{1.7}{1}$

Mr. Xcoder

@totallyhuman No, look at the edited message

Business Cat

@Mr.Xcoder Do we ever have to handle an input like 5? Or would it be 5.0?

Mr. Xcoder

@BusinessCat Choose either 5 or 5.0

Ok well given that, Retina, 5 bytes

python: lambda n:n.split('.')[1]

Mr. Xcoder

Mhm]

TuxCopter

@Mayube Doesn't work for negative numbers

Mayube

works as well as @BusinessCat's retina solution

Business Cat

What is the correct result for -3.7?

TuxCopter

The fractional part needs to preserve the sign iirc

totallyhuman

4:09 PM

lambda n:'-'*(n<0)+'0.'+n.split('.')[1]

Mr. Xcoder

@BusinessCat -0.7

Business Cat

Oh I need to have 0. as well?

Mr. Xcoder

The correct result for -1.7 is -0.7!!!. None of us were correct.

@BusinessCat Yes

Mayube

@Mr.Xcoder Retina, 8 bytes Try it online!

TuxCopter

So the only correct solution is my sed one? nvm

Business Cat

@Mayube Mine still didn't work anyway

TuxCopter

@StepHen Connect it to your TV and a controller and use it as an emulator?

Step Hen

4:11 PM

@Mayube most likely

@TuxCopter yeah probably something like that

officialaimm

@Mr.Xcoder lambda x:x-int(x) would this work??

Socratic Phoenix

@StepHen implement a tape-based OS...

Step Hen

I'll probably take some time to learn non-Windows command line first

Mayube

@officialaimm won't work for negatives

Business Cat

No one did JS yet?

does it work properly in js?

Business Cat

Yes

yes, but not in Python

you guys sure about it not being main-appropriate? 'cause i kinda like the problems that some of the approaches end up having

totallyhuman

@Mr.Xcoder but it takes input

Mr. Xcoder

5:14 PM

ok, do as you wish... But the whole point is compression

DJMcMayhem

It's still KC

dzaima

@totallyhuman wasn't there a meta post about different KC types, one being limited input amount?

Mr. Xcoder

^^

TuxCopter

it's also KC if it takes input iirc

DJMcMayhem

Not always, but the point here is that there's a lot of data (all the OS names) that you need to recreate in as few bytes as possible

Business Cat

5:36 PM

Any language with compressed strings should have a command to compress strings

Or it's too much of a pain to use

Nick Clifford

@BusinessCat command within the language or command exposed by the interpreter?

Business Cat

Either way

TuxCopter

@BusinessCat an interpreter flag yes but a command no

wastes space

Nick Clifford

Ohm just exposes a Ohm::Smaz.compress method from the interpreter

dzaima

@BusinessCat SOGL has a generator (though somewhat manual) for compressed strings because without it it'd take ~50 minutes to get something like the android version string

Business Cat

5:39 PM

The only problem, imo, with have a function from the interpreter is that the user has to know how to use the language the interpreter is written in in order to call it

totallyhuman

you just put a string in verbose mode in charcoal and it'll compress for you

Business Cat

I had to look up how to call a Ruby function to use Ohm's
