I voted for '!=', but I also know of '<>' and '-ne'.

!= because the exclamation point is widely used in programing to mean "does/is not".

The last two are an attempt to replicate the standard handwritten symbol, which does exist in LaTeX as a single symbol:

not equal.png [ 220 Bytes | Viewed 1918 times ]


Lacking such a symbol, the proper formal way to express the relationship is to use the logical NOT operator before the equal sign. !=

Now we need a unicode for "Does not want!"

!=

I've seen <> and it always confuses me for a second.

I've used != and <>

I believe I picked up the use of <> from BASIC.

BASIC is the only language I'm aware of that uses "<>".

Trivia: in Intel-style x86 and x64 assembly, you do (in)equality testing with a combination of the cmp or sub instruction followed by jz/je or jnz/jne.

Code:
cmp eax, 7h
jne <wherever>

Non of the above.

I typically use |= when typing. Tho /= is a close runner up.

I want to say that Pascal uses (or used to use) <> for an inequality operator.

I voted for !=, but my job has me using <> an awful lot.

Oh, also ... NEQ.

Sorry to burst your bubble, Midgen but ...

<> == !=

And the logic is perfectly sound.
>= .... greater than or equal to
<= .... less than or equal to
<> .... less than or greater than (aka: not equal to)

Sorry bout that. It's totally funny, now that I know it's not a deeply-held personal belief.

Definitely !-, followed by <>.

I originally learned to program in BASIC which uses <>, but many years of programming in C, then C++, then Java, have ingrained !=.

!= clearly means you are excited that it is equal.

My programming days are long behind me. I use /=

!= and I think as above both Pascal and Basic use <> but I haven't used that in a longgggggg time.
