Operators

An operator is an element that performs an operation on one or more code values.
Relational operators are used to compare values and are evaluated from left to right.
If you type in "=<" or "=>" then it will be automatically changed to ">=" or "<=".

Arithmetic Operators

+ (plus)	Addition (3 + 3)
- (minus)	Subtraction (6 - 3)
* (multiply)	Multiplication (3 * 2)
/ Division	Decimal Division (10 / 3) This is the normal division operator
\ Division	Integer Division (9 \ 3), rounded down This operator is not available in C# or JavaScript
Exponentiation	(3 ^ 3)
MOD	Returns the remainder after division operator (12 Mod 3)

Logical Operators

AND	The logical "AND" operator (Boolean).
OR	The logical "OR" operator (Boolean).
NOT	The logical "NOT" operator (Boolean).
EQV	The logical equivalence operator.
IMP	The logical implication from two values (Variant).
XOR	The logical exclusion operator.

LIKE	The pattern matching operator.
IS	Compares two object reference variables.
TYPEOF	The object data type.

Comparison

Symbol	Operator	Notes
=	Equal to	Returns True if what is on the left is equal to what is on the right. The equal sign is also used as the assignment operator. The compiler figures out which operator to use based on the context of the code.
<>	Not equal to	Returns True if what is on the left is not equal to what is on the right.
>	Greater than	Returns True if what is on the left is greater than what is on the right.
<	Less than	Returns True if what is on the left is less than what is on the right.
>=	Greater than or equal	Returns True if what is on the left is greater than or equal to what is on the right.
<=	Less than or equal	Returns True if what is on the left is less than or equal to what is on the right.
Is	Reference equity	Returns True if the object reference on the left is the same instance as the object reference on the right. This operator can be used with Nothing.

Precedence

When a series of operators appear in the same expression there is a strict order in which they will be evaluated.
The rules of precedence tell the compiler which operators to evaluate first.
If several operators exist in a single expression and parentheses have not been used then the expression is evaluated in a strict order.
This order is known as operator precedence.
When operators have the same precedence they are evaluated from left-to-right.
Parentheses can obviously be used to change the order of precedence.
Operations inside parentheses are always performed before those on the outside.

Order	Symbol	Operator
1	^	Exponentiation
2	-	Negation
3	*	Multiplication
3	/	Division with Decimal result
4	\	Division with Integer result
5	Mod	Modulo
6	+	Addition
6	-	Subtraction
7	&	String Concatenation
8	=	Equal or Assignment
8	<>	Not Equal To
8	<	Less Than
8	>	Greater Than
8	<=	Less Than or Equal To
8	>=	Greater Than or Equal To
9	NOT	Not
10	AND	And
11	OR	Or
12	XOR	Exclusive OR
13	EQV	Equivalence
14	IMP	Implication
