what is the '¬' character called and what is it for


I don't ever think I ever have a need to type this character "¬".

So I was wondering what it is called and what it is for, and why it is on the my keyboards (both my UK and EU keyboards)?

I assume that it had some common function back in the 1970's, maybe.

I'm curious what that might be as I'm almost completely certain that I have never typed this character once in over 25 years for anything.

I do use the tilde character "`", a lot. But never the shift-variant on that key of the "¬".

Part of the reason that I am asking this is because that I might use it as an AutoHotkey trigger, since it was so useless to me, but I was curious about what its purpose might be, etc.. before I do that.


Solution

  • It's the logic negation symbol.

    It's used in some programming languages as a mean to negate a boolean value, particulary old languages
