Operators
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
