Precedence

Operator precedence describes the order in which operations are performed in an arithmetic expression.

The numbers are called operands, and the operation is defined by the operator.

Priority	Operator	Description	Example
0	>> << |>	Connection Operators	Test1 > 0 >>
1	()	Expression grouping	(3 + 4)
2	[]	Attribute Table field	Attribute[columnA]
2	()	Function call	Function()
2	{}	Keywords	{PreviousCase}:test1
2	;	Attributes definition separator	Function(par1; par2)
2	!	Unit of measure operator
3	*	Multiplication	10 * 5
3	/	Division	10 / 5
3	@	Division Remainder	10 % 5
4	+	Addition	10 + 5
4	-	Subtraction	10 - 5
5	<	Less than	x < y
5	<= =<	Less than or equal	x <= y
5	>	Greater than	x > y
5	>= =>	Greater than or equal	x >= y
5	=	Equal	x = y
5	<>	Not Equal	x <> y
6	AND	Logical AND
6	OR	Logical OR
6	XOR	Logical XOR
