ASP
Operators
ASP is programmed in VBScript
by default, thus ASP's operators
are VBScript operators by default.
Operators in ASP fall into four
categories Math, Comparisons, the
somewhat more advanced Logic
operators, and Leftovers(those
that don't fit well into any
category).
ASP Arithmetic Operators
The mathematical operators in
ASP are similar to many other
programming languages. However,
ASP does not support shortcut
operators like ++, --, +=, etc.
| Operator |
English |
Example |
Result |
| + |
Addition |
myNum = 3 + 4 |
myNum = 7 |
| - |
Subtraction |
myNum = 4 - 1 |
myNum = 3 |
| * |
Multiplication |
myNum = 3 * 2 |
myNum = 6 |
| / |
Division |
myNum = 9 / 3 |
myNum = 3 |
| ^ |
Exponential |
myNum = 2 ^ 4 |
myNum = 16 |
| Mod |
Modulus |
myNum = 23 Mod 10 |
myNum = 3 |
| - |
Negation |
myNum = -10 |
myNum = -10 |
| \ |
Integer Division |
myNum = 9 \ 3 |
myNum = 3 |
Comparison Operators
Comparison operators are used
when you want to compare two
values to make a decision.
Comparison operators are most
commonly used in conjunction with
"If...Then" and "While something
is true do this..." statements,
otherwise known as conditional
statements. The items that are
most often compared are numbers.
The result of a comparison
operator is either TRUE or FALSE.
| Operator |
English |
Example |
Result |
| = |
Equal To |
4 = 3 |
False |
| < |
Less Than |
4 < 3 |
False |
| > |
Greater Than |
4 > 3 |
True |
| <= |
Less Than Or Equal To |
4 <= 3 |
False |
| >= |
Greater Than Or Equal To |
4 >= 3 |
True |
| <> |
Not Equal To |
4 <>3 |
True |
Logical Operators
The above comparison operators
result in a truth value of TRUE or
FALSE. A logical operator is used
for complex statements that must
make decisions based on one or
more of these truth values.
| Operator |
English |
Example |
Result |
| And |
Both Must be TRUE |
True and False |
False |
| Or |
One Must be TRUE |
True or False |
True |
| Not |
Flips Truth Value |
Not True |
False |
String Operators
The only string operator is the
string concatenation operator "&"
that takes two strings and slams
them together to form a new
string. An example would be
string1 = "Tim" and string2 = " is
a Hero". The following code would
combine these two strings into
one: string3 = string1 & string2
| Operator |
English |
Example |
Result |
| & |
String Concatenation |
string4 = "Bob" & " runs" |
string4 = "Bob runs" |
We will be using these
operators throughout the tutorial,
so chances are you will get
understand them more and more as
this tutorial goes on.
