@NewPosts it was fun creating non-built-in answers that act in the most goofy ways :p

We honestly don't have enough Bignum challenges

I've just come up with a cursed challenge idea: Golf the median of the chi-squared distribution χ²(1).

There is no simple closed form of that.

We should have more challenges regarding floating-point numbers.

Though C++ is gonna just invoke reinterpret_cast, ironically, higher-level languages is going to suffer.

AFAIK, Haskell's unsafeCoerce is not reinterpret_cast so

ATaco

Ah yes, BitConverter.ToFloat(BitConverter.ToBytes(i)), a nice and short way to represent (float)(void*)i

Dannyu NDos

What language is that? C# I guess?

ATaco

C#.

Java has a similar expulsion as a solution IIRC.

Gmod Lua, Returns via Callback.

function(i,cb)util.AddNetworkString"s"net.Receive(s,function()cb(net.ReadFloat())end)net.Start"s"net.WriteInt(i)net.Broadcast()end

(Only works in Singleplayer)

i cba to look up how to do c++ `reinterpret_cast`, but

Still worth a challenge tho

Related fun fact: The GHC.Exts module in Haskell has unsafeCoerce#, which reinterpret_casts not only types, but also kinds. Never use it.

Nvm, this challenge is solvable without unsafeCoerce. I can do 0.454936423119572751942516646979649 :: Float.

To speak more seriously, most Haskellers don't care about the "magical" sides of Haskell. So IDK, I mean.

@UnrelatedString Does that mean Int in TIO is 32 bits long??

noodle man

i just VTCd a question for the wrong reason, but when i retracted it now i can't VTC it for the right reason :o

vtcs be like that

noodle man

do you think this challenge should be closed?codegolf.stackexchange.com/questions/39752/…

i think it should be a dupe of rickroll

Unrelated String

@DannyuNDos no

there's probably just either some stronger constraint stopping the other half from being garbage or it's a total coincidence

Dannyu NDos

Maybe the "garbage" was zero-initialized from the start? Who knows...

@NewPosts The lack of edit indicator on mobile makes this even better

I saw the edit indicator and thought "aw did another mod edit my edit to a different joke?"

and then realised "oh no wait a minute no that's my edit to the original message"

forgetting that of course my edit would make the indicator show :p

^ is a way more simplified version of what I had to do for an assignment

I had to account for different arrival times, different scheduling algorithms in the one simulation, priorities, pre-empting based on priorities, and a whole bunch of process stats :p

Oracle Solaris

Solaris is a proprietary Unix operating system originally developed by Sun Microsystems. After the Sun acquisition by Oracle in 2010, it was renamed Oracle Solaris.Solaris superseded the company's earlier SunOS in 1993, and became known for its scalability, especially on SPARC systems, and for originating many innovative features such as DTrace, ZFS and Time Slider. Solaris supports SPARC and x86-64 workstations and servers from Oracle and other vendors. Solaris was registered as compliant with the Single UNIX Specification until 29 April 2019.Historically, Solaris was developed as proprietary...

I find it amusing that Oracle has an operating system that allows multiple processes with multiple threads while their most famous product (Java) only allows one process with multiple threads :p
