#### 0x vs. $

The wiki currently doesn't have a consistent way of denoting hexadecimal values. Some pages use 0x, some use $, and some both! I'm not sure what the best solution to this is, or if there necessarily needs to be one.
What do you all think about the symbols? Do we keep tempting our lurkers over at the stock exchange, or opt for its more bovine counterpart? Could one be used specifically for denoting an address, and the other a value?

If the reader does not know the meaning of one, they most likely will not know the meaning of the other. The contrary applies - if one knows and comprehends the meaning of one, the other should be under their belt as well.
I'm under the impression that if clarification is needed, it can be provided in brief. They both denote the same thing, so i'm sure it won't be an issue. Consistency between one or the other may even cause minor problems, as there as there as some familiar with 0x and others familiar with $.
That's my 0.02¢.

I've voted $ for addresses and 0x for values, loosely following the 6502 spec (where $2A is address 422, and #$2A is value 42)
I believe it's important to differentiate both of those.

no one has said shit about the "h" suffix

Don't believe it's ever been used on the wiki, but I added the "Something else" option for things like that, as unlikely as it is we'd consider making it the standard.
Good input so far, guys! I think I'll need to hear more before forming an opinion on this myself.

The "h" prefix is barely used, and just plain stupid. I'm against it.

To whoever voted 0x for everything, any particular reason?

see, look. It looks good, better than 0x or $, anyway

Has there ever been a programming language that's used $ for hexadecimal? Where did $ even start?
Of course I can tell $ is hexadecimal if it's in context but I don't see a reason to use a symbol that means other things (e.g. currency, Perl/shell/PHP variables) when 0x doesn't mean anything else as a prefix.
I don't see the point in differentiating addresses and values because you need context anyway.

Fast identification.

Assembly.

If context matters, this is a moot point.

The letter is even less distinguishable here. Especially if you went with lowercase letters.

Yeah, the thing is there is that the h visually blends in with the hex letters. 0 and x have naturally distinct shapes so they'll stand out.
Also I just realised now this is Wiki Discussion and not Debate Wars w h o o p s

0 is a valid hex character.

I'm tired and a bit cooked, yeah. Well, the x part holds true.

And besides, prefixing gives metadata before the number, which facilitates comprehension (you can gather it immediately from CAFEh, but not from 1337h)
