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.
|+||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 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.
|=||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|
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.
|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|
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
|&||String Concatenation||string4 = “Bob” & ” runs”||string4 = “Bob runs”|
