Comment On Floor -1

“A popular job interview question goes something like, ‘program me an elevator control system,’” Stephen writes, "apparently, the elevator company never thought to ask their programmers that question." [expand full text]

Note from Alex: Impossible... rememer that (null) is not nothing, not something, and not anything. (null) cannot be seen and (null) cannot not be seen. So, therefore, you all must have immagined a (null) article.

So if zero takes you to the ground floor, where does 1 take you? The 2nd floor?

In the UK at least the 1st floor is above the ground floor.

Programmers should at least appreciate the logic behind the elevator one (zero-based floors). But I'm not sure whether that's the WTF here (at least I don't think it's a failure). Maybe that there's no -1 button?

Yes. As you can see a programmer obviously designed this. And all us programming folk know that 0 IS the first integer.

Actually, it's mostly just Europe (and Quebec... weirdos) that use the "1st floor is the floor above ground" system. North America (except Quebec. Seriously, WTF guys?), Russia and Asia use the "ground floor is first floor" system. I think Australia also uses British terms. Hong Kong appears to be split 50/50.
That just leaves South America and Africa as the deciding votes. I wasn't able to find any information on how they number their floors.

lern2read.

Carl T says the first floor is the one above the ground floor in a lot of countries (not quite as many as he states, but still a considerable number). You then say he's wrong, giving Danish as an example, where the first floor (første sal) is indeed the one above the ground floor (stueetage).

In South America we use the smart system too. Above the ground floor there's the first floor. I believe Africa must be the same.

Hey America what's up with the 1-based floor numbering? Do you base your numbering system on roman numerals? Not the smartest system today eh?

I have always stated it as a Ponderable, why an elevator in a two-story building (like many American shopping malls) has two buttons inside the compartment (one for up and one for down).
When you enter such an elevator you have NO CHOICE where you will go. I propose there be NO BUTTONS (maybe just one that says, "GO")

well, seeing as floors are discrete integers, I don't think an irrational number, such as pi, would be very useful...

I have one of those keypads where I work, and it's exactly that: a standard keypad. You press '-' and '1' to go to the first basement, '1' '0' for the tenth floor, etc (bonus points: '*' yields -1, as a shortcut). The only WTF is that the mezzanine between 0 and 1 is floor 100 :): And yes, at least in Portugal we use zero = ground for our floor denominations too.

Thats funny because here where i live, in Denmark, we do actually call it 'stueetage' (ground floor) and then first floor. But perhaps its more a local thing than a national thing.

Retarded are those who assume that every european country is english speaking. In some other languages the elevator buttons don't show the FLOOR number, but a number of "upstairs", thus 0 is the ground floor and 1 the one above it. Some languages even have two different words, one for "floor" and one for "upstairs".

Btw TRWTF is that it's a numpad instead of one number per floor.

Oh, and also, those keypads are outside the elevators, and the choice of which elevator will answer your request is decided in software, and reported on the little LCD above. The real WTF is that, for such a sophisticated system, the distribution software is particularly daft.

The wheelchair button probably forces the assignment to pick a "wheelchair-friendly" elevator in case you have different sizes (never had to use it).

It's actually quite intuitive. Building X has 3 floors. We count them: 1 floor, 2 floor, 3 floors! AH AH AH!
With the floor on the ground, the one we point to and count "1", that's the first floor. The one above that, we point to and say "2"; that's the second floor. We then point one higher, and say "3", the third floor.
I'm sure someone can equally justify the "ground zero" system: it's just two ways of thinking.
But please stop referring to it as the American system. The point I'm trying to make is that significantly more countries than just the US use it, and it's quite insulting to be casually lumped in with them.

Yes, that's my guess as well [though you might want to take a better look at that 'enter' button :)]. My point was: where's the WTF? The only one I can think of is the wording on the note, that says you should be able to press a single button. (So that would make a /very/ minor WTF.)

Anyway, the fact that the elevator actually needs a printed instruction shows that controlling it is apparently not intuitive enough, I'll give Alex that.
