Erlang Bitwise Operators

The following are the bitwise operators available in Erlang.

S.No.	Operator & Description
1	band 　Bitwise 'and' operator
2	bor Bitwise 'or' operator
3	bxor Bitwise 'xor' or exclusive OR operator
4	bnot 　Bitwise NOT operator

The following is the truth table for 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 block shows how to use various operators.

Online Example

Example

-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:
