Operators

Comparison Operators

Used to compare expressions in IF and LOOP statements

Operator	Description	True if	False if
<	Less than	expression1 < expression2	express
<=	Less than or equal to	expression1 <= expression2	express
>	Greater than	expression1 > expression2	express
>=	Greater than or equal to	expression1 >= expression2	express
=	Equal to	expression1 = expression2	express
<>	Not equal to	expression1 <> expression2	express

Arithmetic Operators

Used to assign values to variables

Operator	Description	Applies To
+	Sums two numbers or concatenates two strings.	Integer, String
-	Performs subtraction of two expressions.	Integer
*	Multiplies two expressions.	Integer
\ or /	Divides two expressions.	Integer
<<	Left shifts the bits of an expression.	Integer
>>	Right shifts the bits of an expression.	Integer

Logical Operators

Used to perform bitwise logical operations. These only apply to integers

Operator	Description	Function
AND	Performs a bitwise AND between two values or variables.	*expression1*	*expression2*	*result*
		0	0	0
		0	1	0
		1	0	0
		1	1	1
OR	Performs a bitwise OR between two values or variables.	*expression1*	*expression2*	*result*
		0	0	0
		0	1	1
		1	0	1
		1	1	1
XOR	Performs a bitwise XOR between two values or variables.	*expression1*	*expression2*	*result*
		0	0	0
		0	1	1
		1	0	1
		1	1	0

Operator Precedence

When several operations occur in an expression, each part is evaluated and resolved in a predetermined order called operator precedence. All operators have equal precedence. Each operation is evaluated as it occurs from left to right. Parentheses can be used to override the order of precedence and force some parts of an expression to be evaluated before other parts. Operations within parentheses are always performed before those outside. Within parentheses, however, equal operator precedence is maintained.
