A binary operator is an operator which takes 2 arguments, as opposed to a unary operations, which take 1 argument.

Below is the list of binary operators:

Operator Effect
= may be used for assignment or comparing 2 values like the == operator
:= forced assignment
<> not equal
& concatenation of strings
* multiplication
*= multiplication of the left operand by the right operand followed by assignment of the result to the left operand
+ addition
+= addition of the left operand to the right operand followed by assignment of the result to the left operand
- subtraction
-= subtraction of the right operand from the left operand followed by assignment of the result to the left operand
/ division
/= division of the left operand by the right operand followed by assignment of the result to the left operand
< less than
<= less than or equal to
== equality
> more than
>= more than or equal to
and logical AND
&& logical AND. The use of AND is preferred for readability.
or logical OR
|| logical OR. The use of OR is preferred for readability.
