Lesson 5 | ASP Arithmetic Operators |

Objective | Create formulas and test constants and variables. |

Sooner or later, in a Web application, you will need to perform mathematical calculations. In a previous lesson, we used the multiplication (

`*`

) and subtraction (`-`

)
operations to perform a discount. Here are other mathematical operators available for use in ASP code:
+ Addition 1 + 2 = 3 - Subtraction 2 - 1 = 1 * Multiplication 6 * 3 = 18 / Division 6 / 3 = 2 \ Integer Division 6.3 \ 3.1 = 2 Mod Modulus 8 Mod 3 = 2 (Any remainder is discarded) ^ Exponentiation 8 ^ 2 = 64

(**NOTE:** This type of division rounds the two numbers to integer values then produces an integer result. Any remaining decimal values are discarded.)

There are also a number of logical operators available for our use.

Two of the most commonly used are

Two of the most commonly used are

- NOT and
- AND.

If Not (A = 5) Then . . . 'If A is NOT equal to 5, 'then something happens 'Can also be written as A <> 5 . . If (A <> 5) AND (A <> 7) Then . . . 'If A is not equal to 5 AND 'A is not equal to 7 'then something happens .
