The negation operator

The negation operator

[ljharb]

Can you provide a code example? x = 3; -x prints out negative three in every ruby console I've ever used.

[RomanMenzel]

No, I mean the '!' operator. An example would be:

if !x == 3
    ...
end

This doesn't work! ☝️

[ljharb]

You want if x != 3 there. negation applies to a value, and !x will never == 3, because !x will always be a boolean true or false.

Ok, now I understand, thank you.
