XOR operator?

[Daniel Carrera]

Hi all,

I'm trying to figure out what the boolean "xor" operator is in Ruby. I
thought it was "^^" but that doesn't work. I searched through PickAxe and
couldn't find a mention of xor.

Does Ruby have an xor?

Cheers,

Does Ruby have an xor?

irb(main):001:0> 1 ^ 0
=> 1
irb(main):002:0> 1 ^ 1
=> 0
irb(main):003:0> 0 ^ 0
=> 0
irb(main):004:0> 0 ^ 1
=> 1

Thanks everyone. Yeah, ^ seems to work.

It's just a single "^" character, e.g.

six = 2 ^ 4

Hope this helps,

Lyle

Thanks everyone. Yeah, ^ seems to work.

[...as an XOR operator]

One should add that the exponentiation operator is '**'.
Matz, does that syntax mean that Ruby also has COBOL or FORTRAN
heritage (I am not aware of anything else that would justify that
assumption)?
