An **Operator** can be defined using a simple expression – 4 + 5 is equal to 9. Here, 4 and 5 are called **operands** and + is called **operator**. VBA supports following types of operators −

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

## The Arithmatic Operators

Following arithmetic operators are supported by VBA.

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

Operator | Description | Example |
---|---|---|

+ | Adds the two operands | A + B will give 15 |

– | Subtracts the second operand from the first | A – B will give -5 |

* | Multiplies both the operands | A * B will give 50 |

/ | Divides the numerator by the denominator | B / A will give 2 |

% | Modulus operator and the remainder after an integer division | B % A will give 0 |

^ | Exponentiation operator | B ^ A will give 100000 |

## The Comparison Operators

There are following comparison operators supported by VBA.

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

Operator | Description | Example |
---|---|---|

= | Checks if the value of the two operands are equal or not. If yes, then the condition is true. | (A = B) is False. |

<> | Checks if the value of the two operands are equal or not. If the values are not equal, then the condition is true. | (A <> B) is True. |

> | Checks if the value of the left operand is greater than the value of the right operand. If yes, then the condition is true. | (A > B) is False. |

< | Checks if the value of the left operand is less than the value of the right operand. If yes, then the condition is true. | (A < B) is True. |

>= | Checks if the value of the left operand is greater than or equal to the value of the right operand. If yes, then the condition is true. | (A >= B) is False. |

<= | Checks if the value of the left operand is less than or equal to the value of the right operand. If yes, then the condition is true. | (A <= B) is True. |

## The Logical Operators

Following logical operators are supported by VBA.

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 the Expression is true. | a<>0 AND b<>0 is False. |

OR | Called Logical OR Operator. If any of the two conditions are True, then the condition is true. | a<>0 OR b<>0 is true. |

NOT | Called Logical NOT Operator. Used to reverse 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 be True, the result is True. | (a<>0 XOR b<>0) is true. |

## The Concatenation Operators

Following Concatenation operators are supported by VBA.

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 both numbers and strings. The output depends on the context, if the variables hold numeric value or string value.
