The examples shown in the preceding table use operators in their expressions. An
operator is a symbol that represents a specific action. Many programs and
programming languages use operators to manipulate numbers and text in
sophisticated ways. The following table specifies the operators available for alarm
filters and their precedence, from highest to lowest, in a logical expression:
Operator Operation

argument. In this aspect a unary minus is used to create a negative
number.

* Multiply.
/ Divide.
% Remainder.
+ Add.
- Subtract.
< Less than.
> Greater than.
<= Less than or equal to.
>= Greater than or equal to.
== Equal.

true.
|| Logical OR: the function which is true if any of its arguments are
