EDIT: Never seen ¬ used for NOT only ~.

~ is approximately....

Reading it again

I think in simple terms its a math symbol for "not"

ie. 7 = ¬8

seven equals not eight

Not quite right, read the first paragraph you quoted:

"... true when p is false and false when p is true... "

"Not 8" is true when 7, but 7 is not necessarily true when "not 8" (it could be 5).

It's basically just a logical "NOT" operator, that is: ¬true = false .

~ is used in programming for NOT but yeah its approximately in written stuff. I've never actually seen ¬ in actual useage.

 

[Randomface74]

but ! == not

impossible to have a cross-discipline discussion about this lol

It's in logic rather than programming I believe.

~ is used in some languages as a bitwise NOT afaik... the syntax for logical NOT in programming is usually !

¬ is a character used in logical proofs (flashbacks to Logic modules... )

Yeah - i.e. if (!blah) { and BITFLAGS &= ~FLAG was getting things a bit confused had a long day :S

I always use != as not equal to, didn't realise there was a dedicated symbol for it!

 

[Westyfield2]

I don't get what's confusing... it's just basic Discrete Mathematics/Logic?

¬(p ∨ q) ≡ (¬p) (¬q)

 

[SilverTongue]

I always wondered what it was now, I think I even less the wiser

Isn't Boolean Algebra the type of music Shayper plays in his dance halls?

I do both of these things.

Boolean algebra is a *****. Had to do a load of Monte Carlo work the other day for coursework, pain in the proverbial.

!= is the best way to do it in many programming languages for not equal to, some (mostly BASIC type languages) use <>. NOT is a little different.

I like boolean algebra and Monte Carlo

I like boolean algebra and Monte Carlo

I hate Numerical Methods, if I had wanted to do computing I'd have chosen maths and computing as a course

Not equal to, is not the same as not.
