Following are the logical operators available in Erlang.
| Operator | Description | Example |
|---|---|---|
| or | This is the logical “and” operator | true or true will give true |
| and | This is the logical “or” operator | True and false will give false |
| not | This is the logical “not” operator | not false will give true |
| xor | This is the logical exclusive “xor” operator | True xor false will give true |
The following code snippet shows how the various operators can be used.
Example
-module(helloworld).
-export([start/0]).
start() ->
io:fwrite("~w~n",[true or false]),
io:fwrite("~w~n",[true and false]),
io:fwrite("~w~n",[true xor false]),
io:fwrite("~w~n",[not false]).
The output of the above program will be −
Output
