This project is very much a work in progress. More operators and symbols to come. That said, if you see any errors or omissions, please let me know on Bluesky, Twitter, or via email.

Bitwise AND Operator

The bitwise AND operator (&) is used to perform a bitwise AND operation on two numbers.

Not what you're looking for? The & symbol is used in several syntactically distinct ways in Ruby. Head over to the Ampersand page to get a lay of the land.

Here is an example of using the bitwise AND operator.

10 & 3 # => 2

> 10.to_s(2)
=> "1010"
> 3.to_s(2)
=> "11"
> (10 & 3).to_s(2)
=> "10"
> 0b10.to_i
=> 2
