Logic operators in LaTeX? (XOR?)

Question

When I google this, it seems that \XOR is how you would get an XOR symbol in LaTeX, however that is giving me the 'undefined control sequence' error. How does one get the xor symbol?

Answer 1

How about \newcommand*\xor{\mathbin{\oplus}}?

Answer 2

\oplus worked for me :)

I found this in List of logic symbols :P

Answer 3

I found a bit lame solution, but it works for me. Just do:

\underline{\vee}

Answer 4

I use this one \overline{\vee}.

Answer 5

What you're looking for is \veebar in amssymb.

\usepackage{amssymb}

$\veebar$

If you like, you can create a new command \lxor, named to match \lor and \land:

\providecommand{\lxor}{\veebar}
