ASP Comparison Operators Logical Operators
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.
