How do you write the not equal sign?

In programming it is often != and I use that. I just saw /= as well today.

What do you use (other than

I have also seen "<>" (less than or greater than)"

I always use != (but then I am a programmer).

Huh! I didn't know Not Equal

existed here...

I think if I saw "foo /= bar" I would interpret it as

foo = foo / bar;

Of the forms that I can write with this keyboard, I have seen != and <>, but never /=.

The semantical standard is !=

I have never seen the /= before either. Where did you see it used? Smile

Then there's the ever popular 'NE'. As opposed to EQ, GT, LT, GE, and LE...

What exactly does this mean: The use of the = symbol in programming requires a new understanding of the terms assignment and equality. (?) Are there any other use for the equal sign in programming other than indicate mathematical or logical equivalence ?

I use != but I've seen <> used in pl sql.

pgp, I think = in programming is mostly used for assignment. Assigning values to variables and such. To check equality, depending on the language, it's usually == (in Java .equals()). There is a big difference between assigning something equal and checking equality.

No, sorry, not well enough to be of any use to you. But if you have a specific question about it I'm sure someone here knows enough to at least point you in the direction of the answer.

I noticed here that typing in ": ! = :" gives the Not Equal

symbol on this board, but not elsewhere.

Is there any way to make this work elsewhere, like on another forum? (like on my Edit [Moderator]: Link removed?).

The " Not Equal

" sign would really be useful to me.

I think /= is some sort of shorthand for =/=

I use ~=, which is from Matlab/Octave, but != is inter-changeable in Matlab, I think.

EDIT: I suppose if you use '~' for 'not', you could also use , er, nevermind, I can't seem to place the symbol here, but it looks like a L rotated 90 degrees forward and then flipped over.

<> is more famous though. Its an old notion.

yah, I have a math book with that in it. sort of like a ",_" except upside down and in the middle of the line.

Just make it an emoticon for the board. Most board software allows you to add emoticons.

@FreeDuck,

Yes, you're right <> is used in SQL and PL/SQL

I use != in sql+ and ne in SAS. Common syntax in SAS would be

if x ne 7 or y gt 8 or z le 6 then...

which translates to

if x not equal to 7 or y greater than 8 or z less than or equal to 6 then...
