| Mathematical Operators
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.)
Logical -Boolean-operators
There are also a number of logical operators available for our use. Two of the most commonly used are
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
.
