VBScript is very flexible when it comes to storing data in variables. You can add variables that contain numbers together, or even concatenate strings. In ASP, we can group operators into four major categories: Arithmetic, Comparisons, Logic and Concatenation.

## Arithmetic

The arithmetic operators used in ASP coding are very similar to other programming languages.

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

+ | Addition | x = 5 + 1 | 6 |

- | Subtraction | x = 5 - 1 | 4 |

* | Multiplication | x = 5 * 1 | 5 |

/ | Division | x = 6 / 3.5 | 1.17428571428571 |

^ | Exponential | x = 3 ^ 3 | 27 |

Mod | Modulus | x = 10 Mod 3 | 1 |

- | Negate | x = -5 | -5 |

\ | Integer Division | x = 6 \ 3.5 | 1 |

## Comparisons

Comparison operators are often used within If..Then blocks of code (conditional statements). They are helpful when you need to compare two variables and make a decision based on the outcome. The result of a comparison operator is either TRUE or FALSE.

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

= | Equal To | 5 = 1 | FALSE |

< | Less Than | 5 < 1 | FALSE |

> | Greater Than | 5 > 1 | TRUE |

<= | Less Than Or Equal To | 5 <= 1 | FALSE |

>= | Greater Than Or Equal To | 5 >= 1 | TRUE |

<> | Not Equal To | 5 <> 1 | TRUE |

## Logic

A logical operator is used in conditional statements that require more than one set of comparisons.

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

And | All Must be TRUE | True and False | FALSE |

Or | One Must be TRUE | True or False | TRUE |

Not | Reverse of True | Not True | FALSE |

## Concatenation

When working with strings, the "&" operator is used to merge strings together to form a new string.

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

& | String Concatenation | myString = "John" & "Smith" | John Smith |

## Example

<!DOCTYPE html> <html> <head> <title>My Page</title> </head> <body> <% Dim x,y x = 5 + 1 y = 1 Response.Write (x & "<br />") If x > 1 Then Response.Write("x is greater than 1!<br />") Else Response.Write("x is not greater than 1!<br />") End If If (x > 1) And (y > 1) Then Response.Write("Both x and y are greater than 1!<br />") Else Response.Write("Either x or y is not greater than 1!<br />") End If Dim firstName Dim lastName Dim fullName firstName = "John" lastName = "Smith" fullName = firstName & " " & lastName Response.write(fullName) %> </body> </html>
