The CueScript language allows for operators to be used in expressions. Operators are symbols that appear in-between two values that “operate” on those values. Common operators include mathematical functions such as + and – for addition and subtraction, and boolean functions such as And, and Or.
Mathematical Operators
The following operators are mathematic, meaning that they perform functions on numbers:
| Operator | Function | Example | Result |
|---|---|---|---|
| + | Addition | 3 + 5 | 8 |
| – | Subtraction | 5 – 3 | 2 |
| * | Multiplication | 3 * 7 | 21 |
| / | Division | 18 / 3 | 6 |
Concatenation Operator
The following operator performs its function on strings. Shared with the Addition Operator, if either side of the “+” is a string, the result will be a string:
| Operator | Function | Example | Result |
|---|---|---|---|
| + | Concatenation | “Cue” + “Server” “CS” + 2 3 + “ is a crowd” |
“CueServer” “CS2” “3 is a crowd” |
Boolean Operators
The following operators are boolean, meaning that they compare two values in a true or false context. Note that the result of a boolean operator will always be either 0 (meaning false) or 1 (meaning true).
| Operator | Function | Examples | Result |
|---|---|---|---|
| == | Equal | 5 == 5 3 == 5 |
1 0 |
| != | Not Equal | 5 != 5 3 != 5 |
0 1 |
| > | Greater Than | 5 > 3 3 > 5 |
1 0 |
| >= | Greater Than or Equal | 5 >= 3 4 >= 4 2 >= 7 |
1 1 0 |
| < | Less Than | 3 < 5 5 < 3 |
1 0 |
| <= | Less Than or Equal | 3 <= 5 4 <= 4 7 <= 2 |
1 1 0 |
| and | Logical And | 0 and 0 0 and 1 1 and 0 1 and 1 |
0 0 0 1 |
| or | Logical Or | 0 or 0 0 or 1 1 or 0 1 or 1 |
0 1 1 1 |
