Re: [swift-users] what's ^ operator for

[Saagar Jha via swift-users]

The ^ operator performs a bitwise XOR 
. This is not the same as 
exponentiation.

[swift-users] what's ^ operator for

[Mr Bee via swift-users]

Hi all, I wrote this in XCode Playground…
let i = 2^2print(i)
It runs fine without any errors and print 0, while I expect it to print 4 from 
2 power by 2 or 2². Swift ebook and even Google gave me nothing on this.
What did I miss?
Thank you.
Regards,
–Mr Bee
