# 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 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 −

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 Try it yourself.

## 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 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 −

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.

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