An operator in a programming language is a symbol that tells the compiler or interpreter to perform specific mathematical, relational or logical operation and produce final result.

Operators | Meanings | Operators | Meanings |
---|---|---|---|

+ | Addition | >= | Greater than or equal to |

- | Subtraction | <> | Not equal to |

* | Multiplication | = | equal to |

/ | Division | & | String Concatenation |

\ | Integer Division | And | Logical And |

Mod | Modulo Division | Not | Logical Not |

< | Less than | Or | Logical Or |

> | Greater than | Xor | Logical Xor |

<= | Less than or equal to | ^ | Power |

### Assigning values to variables : '=' operator

The Assignment operator (=) is used to assign a value or an expression to a variable. When you assign a value, its not the same as the Equal to operation, but the value is copied to a variable. Besides assigning values and expressions, you can assign a variable to a variable also.

#### Example

x=a+b

'=' , '+' are the operators.

x,a,b are the operands and 'a+b' is an expression. x=a+b is a statement.

The following program will print 20.

Private Sub cmdDisplay_Click() Dim num As Integer, r As Integer, n As Integer n = 10 r = n ^ 2 'n to the power 2 num = n + r / n Print num End Sub

Output : 20

### The Integer Division Operator ('\')

The Integer Division operator('\') eliminates the decimal part after division.

#### Example

Private Sub cmdDivision_Click() Dim a As Double, b As Double, c As Double a = 12: b = 5 c = a \ b Print c End Sub

Output : 2

### The 'Mod' operator

The Mod operator is used to calculate remainder.

Example :

Private Sub cmdShow_Click() Dim remainder As Integer, num As Integer num = 21 remainder = num Mod 10 Print remainder End Sub

Output : 1

### Boolean Operators : And, Or, Not, Xor

To learn about Boolean operators, you first need to have the concept of If-Else condition. So Boolean operators are explained in a later lesson.
