Following are the Arithmetic operators available in Erlang.
| Operator | Description | Example |
|---|---|---|
| + | Addition of two operands | 1 + 2 will give 3 |
| − | Subtracts second operand from the first | 1 – 2 will give -1 |
| * | Multiplication of both operands | 2 * 2 will give 4 |
| / | Division of numerator by denominator | 2 / 2 will give 1 |
| rem | Remainder of dividing the first number by the second | 3 rem 2 will give 1 |
| div | The div component will perform the division and return the integer component. | 3 div 2 will give 1 |
The following code snippet shows how the various operators can be used.
Example
-module(helloworld).
-export([start/0]).
start() ->
X = 40,
Y = 50,
Res1 = X + Y,
Res2 = X - Y,
Res3 = X * Y,
Res4 = X / Y,
Res5 = X div Y,
Res6 = X rem Y,
io:fwrite("~w~n",[Res1]),
io:fwrite("~w~n",[Res2]),
io:fwrite("~w~n",[Res3]),
io:fwrite("~w~n",[Res4]),
io:fwrite("~w~n",[Res5]),
io:fwrite("~w~n",[Res6]).
The output of the above program will be −
Output
90 -10 2000 0.8 0 40
