VBScript - Operators

What is an operator?

Simple answer can be given using expression 4 + 5 is equal to 9. Here, 4 and 5 are called operands and + is called operator. VBScript language supports following types of operators:

  • Arithmetic Operators
  • Comparison Operators
  • Logical (or Relational) Operators
  • Concatenation Operators

The Arithmetic Operators

There are following arithmetic operators supported by VBScript language:

Assume variable A holds 5 and variable B holds 10, then:

Show Examples

Operator Description Example
+ Adds two operands A + B will give 15
- Subtracts second operand from the first A - B will give -5
* Multiply both operands A * B will give 50
/ Divide numerator by denumerator B / A will give 2
% Modulus Operator and remainder of after an integer division B MOD A will give 0
^ Exponentiation Operator B ^ A will give 100000

To understand these operators in a better way, you can Try it yourself.

The Comparison Operators

There are following comparison operators supported by VBScript language:

Assume variable A holds 10 and variable B holds 20, then:

Show Examples

Operator Description Example
== Checks if the value of two operands are equal or not, if yes then condition becomes true. (A == B) is False.
<> Checks if the value of two operands are equal or not, if values are not equal then condition becomes true. (A <> B) is True.
> Checks if the value of left operand is greater than the value of right operand, if yes then condition becomes true. (A > B) is False.
< Checks if the value of left operand is less than the value of right operand, if yes then condition becomes true. (A < B) is True.
>= Checks if the value of left operand is greater than or equal to the value of right operand, if yes then condition becomes true. (A >= B) is False.
<= Checks if the value of left operand is less than or equal to the value of right operand, if yes then condition becomes true. (A <= B) is True.

The Logical Operators

There are following logical operators supported by VBScript language:

Assume variable A holds 10 and variable B holds 0, then:

Show Examples

Operator Description Example
AND Called Logical AND operator. If both the conditions are True then Expression becomes true. a<>0 AND b<>0 is False.
OR Called Logical OR Operator. If any of the two conditions are True then condition becomes true. a<>0 OR b<>0 is true.
NOT Called Logical NOT Operator. Use to reverses the logical state of its operand. If a condition is true then Logical NOT operator will make false. NOT(a<>0 OR b<>0) is false.
XOR Called Logical Exclusion. It is the combination of NOT and OR Operator. If one, and only one, of the expressions evaluates to True, result is True. (a<>0 XOR b<>0) is false.

To understand these operators in a better way, you can Try it yourself.

The Concatenation Operators

There are following Concatenation operators supported by VBScript language:

Assume variable A holds 5 and variable B holds 10 then:

Show Examples

Operator Description Example
+ Adds two Values as Variable Values are Numeric A + B will give 15
& Concatenates two Values A & B will give 510

Assume variable A="Microsoft" and variable B="VBScript", then:

Operator Description Example
+ Concatenates two Values A + B will give MicrosoftVBScript
& Concatenates two Values A & B will give MicrosoftVBScript

Note: Concatenation Operators can be used for numbers and strings. The Output depends on the context if the variables hold numeric value or String Value.
