LSL Operators

Operators are used to cause an operation (or mathematical action) to be performed on two operands. The easy and common example is 1 + 2 where 1 and 2 are operands, and the + is the operator.

This concept can be extended much further with LSL since operands can be variables with the special case of the assignment operators requiring that the left hand side be a variable.

Operator	Description	Usage Example
() [] .	Parenthesis, Brackets, and Dot	do this second (do this first)
(type)	Typecasting	message = "The result is:" + (string) result;
! ~ ++ --	NOT, One's Complement, Increment, Decrement	counter++;
* / %	Multiply, Divide, Modulus	rollover = (count + 1)%5;
-	Subtraction	one = 3 - 2;
+	Addition or joining Strings	two = 1+1; text = "Hello" + "World";
+	Concatenation or joining Lists	myList = [1, 2, 3] + [4, 5]; newList = oldList + addList;
<< >>	Left Shift, Right Shift	eight = 4 << 1;
< <= > >=	Less Than, Less Than Or Equal To, Greater Than, Greater Than or Equal To	isFalse = (6 <= 4);
==  !=	Comparison Equal, Comparison Not Equal	isFalse = ("this" == "that");
&	Bitwise AND	zero = 4 & 2; four = 4 & 4;
^	Bitwise XOR	zero = 4 ^ 4; six = 4 ^ 2;
|	Bitwise OR	four = 4 | 4; six = 4 | 2;
&&	Comparison AND	isFalse = (FALSE && TRUE);
||	Comparison OR	isTrue = (FALSE || TRUE);
= += -= *= /= %=	Assignment	four = 4;
