Operational expressions are typically used to manipulate data in computer programs.
They support activities such as:
 |
Arithmetic |
|
Comparison |
|
Concatenation |
|
Logical |
Arithmetic
Operators used to
perform mathematical calculations.
Example: C = A * B
|
^ —Exponent Operator |
|
* —Multiply Operator |
|
/ —Division Operator |
|
\ —Division, Return Integer Operator |
|
Mod —Modulo Operator |
|
+ —Add Operator |
|
- —Subtract Operator |
Comparison
Operators used to
perform comparisons of numbers, strings, etc..
"cat and dog" <> "kitten and pup"
(usually found in if-then statements)
|
= —Equal (== is used in C, Java, JavaScript) |
|
<> —Not Equal (!= is used in C, Java, JavaScript) |
|
< —Less Than |
|
> —Greater Than |
|
<= —LessThan or Equal |
|
>= —Greater Than or Equal |
Concatenation
Operators used to
combine strings.
Newstring = "the time is " & Now (Now is a function that
returns the current time).
|
+, & for combining strings |
Logical Operators
Operators used to
perform logical operations.
(A * B) AND (C * D) (usually found in if-then statements)
|
And Operator (&& is used in C, Java, JavaScript) |
|
Not Operator |
|
Or Operator (|| is used in C, Java, JavaScript) |
