VBScript - Operators
What is an operator?
Let’s take an expression 4 + 5 is equal to 9. Here, 4 and 5 are called operands and + is called the operator. VBScript language supports following types of operators −
Arithmetic Operators
Comparison Operators
Logical (or Relational) Operators
Concatenation Operators
The Arithmetic Operators
VBScript supports the following arithmetic operators −
Assume variable A holds 5 and variable B holds 10, then −
| 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 spanision | B MOD A will give 0 |
| ^ | Exponentiation Operator | B ^ A will give 100000 |
To understand these operators in a better way, you can .
The Comparison Operators
There are following comparison operators supported by VBScript language −
Assume variable A holds 10 and variable B holds 20, then −
| 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. |
To understand these operators in a better way, you can .
The Logical Operators
There are following logical operators supported by VBScript language −
Assume variable A holds 10 and variable B holds 0, then −
| 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 is True, then condition becomes True. | a<>0 OR b<>0 is true. |
| NOT | Called Logical NOT Operator. It reverses the logical state of its operand. If a condition is True, then the Logical NOT operator will make it 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 true. |
To understand these operators in a better way, you can .
The Concatenation Operators
There are following Concatenation operators supported by VBScript language −
Assume variable A holds 5 and variable B holds 10 then −
| 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.
