Erlang - Bitwise Operators

Following are the bitwise operators available in Erlang.

Sr.No.	Operator & Description
1	band This is the bitwise “and” operator
2	bor This is the bitwise “or” operator
3	bxor This is the bitwise “xor” or Exclusive or operator
4	bnot This is the bitwise negation operator

Following is the truth table showcasing these operators −

p	q	p & q	p \| q	p ^ q
0	0	0	0	0
0	1	0	1	1
1	1	1	1	0
1	0	0	1	1

The following code snippet shows how the various operators can be used.

Example

Live Demo

-module(helloworld). 
-export([start/0]). 

start() -> 
   io:fwrite("~w~n",[00111100 band 00001101]), 
   io:fwrite("~w~n",[00111100 bxor 00111100]), 
   io:fwrite("~w~n",[bnot 00111100]), 
   io:fwrite("~w~n",[00111100 bor 00111100]).

The output of the above program will be −
