The Weird and The Wonderful

   

The Weird and The Wonderful forum is a place to post Coding Horrors, Worst Practices, and the occasional flash of brilliance.

We all come across code that simply boggles the mind. Lazy kludges, embarrassing mistakes, horrid workarounds and developers just not quite getting it. And then somedays we come across - or write - the truly sublime.

Post your Best, your worst, and your most interesting. But please - no programming questions . This forum is purely for amusement and discussions on code snippets. All actual programming questions will be removed.

It's 2021, and the IRONY flows freely in all things... I expected to see a macro (written in JavaScript), that writes the javascript file: for (x..) if x % 1 == 0 write "if (number == " + x +") return false;" else write "if (number == " + x +") return true;" == And to see him asking people to crowd source running that file, to help him out! == Next question... Where is his test harness... Or is he caught in an infinite loop?

Is the one with that request trolling him? Or does he really needs it for his usage? M.D.V. If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about? Help me to understand what I'm saying, and I'll explain it better to you Rating helpful answers is nice, but saying thanks can be even nicer.

So Brits in the example above, Twelve whats? I’ve given up trying to be calm. However, I am open to feeling slightly less agitated. Re: That's one way to do it Richard Deeming18-Aug-21 22:08 Richard Deeming 18-Aug-21 22:08  Not in British English (or just "English", as it's known). "One hundred and twelve" === 112, not 100.12. "These people looked deep within my soul and assigned me a number based on the order in which I joined." - Homer Re: That's one way to do it John Wellbelove18-Aug-21 22:41 John Wellbelove 18-Aug-21 22:41  The British English convention is to put an 'and' between any hundreds and non-zero tens/units and 'point' to indicate the fraction part. Therefore 123,456.789 is...

But it actually turns out that they have helpfully written one. Here it is if anyone else needs it -> odd numbers[^] A real godsend! “That which can be asserted without evidence, can be dismissed without evidence.” ― Christopher Hitchens Re: That's one way to do it Sander Rossel29-Aug-21 2:50 Sander Rossel 29-Aug-21 2:50  Just what I was looking for! My own isEven function only goes to 1000, this is a huge step forward Just need to brace it properly and remove all those function exits... JavaScript function isEven(number) { let result; if (number === 1) { result = false; } else if (number === 2) { result = true; } else if (number === 3) { result = false; } // ... return result; } And they have an is-odd package which is consistent with this one too. As programmers we know how important it is to be consistent. Thanks for this great find!

QuakeIII: Fast Inverse of Sqrt in C (float to long) raddevus28-Jul-21 9:59 raddevus 28-Jul-21 9:59  Watched video Fast Inverse Square Root — A Quake III Algorithm - YouTube[^] It's a long video about how Quake III dev created a fast inverse of sqrt for 3D transforms. Yes, I watched the video but I don't understand it completely. First the Source Code Here's my source code I used to confirm this weird syntax which... Makes C Think the Address Contains a Long Even Though It's a Float This is not a cast of a float value to long -- which would truncate decimal portion. This is a conversion of the float bits to an address which is a long. The bits stay in tact. !!!! I hope this gets your attention. Third Line Syntax Is WEIRD Really look at the third line below. C++ float fVal = 13.3892F; printf("Float value ==> fVal :%f\n",fVal); long lVal = * (long *) &fVal; printf("float as long ==> lVal: %ld\n", lVal); That 3rd line takes the address of the float &fVal and what!?! multiplies it times a long pointer? or something?!? The Point But the point is, that after you do that, C compiler believes that you've converted the bits that represented the float value into a long. CRAZY!!! I've never seen that syntax before. Here's the output: Float value ==> fVal :13.389200 float as long ==> lVal: 5391137322 Here's a snapshot of what the narrator in the video says. Really funny (read the caption in the snapshot explaining how/why C convert float bits to long). https://i.stack.imgur.com/YHyR5.png[^] PS - If you already knew this, you are a freaking C genius. Seriously. Or, you've been completely tortured by C. EDIT / UPDATE Oh, the syntax is easier than I thought. It casts the float address as a long* and then gets the value stored at (*) that address and stores it at the address of the long -- which is actually the original address of the float (but now converted to a long).

The "kosher" version looks like this: C++ union { float f; long n; /* don't use "l", for readability */ } mixup; mixup.f = floatval; longval = mixup.n; Software rusts. Simon Stephenson, ca 1994.
