Operators

Macro expressions can contain several different operators. They can be used for assignments, comparisons, arithmetic or logical operations and string concatenations. Following is a list of all the operators. Operators can be operating on one (unary), two (binary) or three (ternary) sub expressions:

Operator	Name	Type
Arithmetic Operators
+	Addition	binary
–	Subtraction	binary
*	Multiplication	binary
/	Division	binary
%	Modulo	binary
–	Unary Minus	unary
+	Unary Plus	unary

Increment/Decrement Operators
Operator	Name	Type
++$v	Pre-Increment	unary
––$v	Pre-Decrement	unary
$v++	Post-Increment	unary
$v––	Post-Decrement	unary

Assignment Operators
Operator	Name	Type
=	Assignment	binary
+=	Addition Assignment	binary
–=	Subtraction Assignment	binary
*=	Multiplication Assignment	binary
/=	Division Assignment	binary
%=	Modulo Assignment	binary
&&=	Logical And Assignment	binary
\|\|=	Logical Or Assignment	binary
&=	Concatenation Assignment	binary

Comparison Operators
Operator	Name	Type
==	Equals	binary
!=	Not Equals	binary
<	Less Than	binary
<=	Less Than or Equals	binary
>	Greater Than	binary
>=	Greater Than or Equals	binary

Logical Operators
Operator	Name	Type
&&	Logical And	binary
\|\|	Logical Or	binary
!	Logical Not	unary

String Concatenation Operator
Operator	Name	Type
&	Concatenation	binary

Ternary Operator
Operator	Name	Type
?:	Ternary Operator	ternary

Operator Precedence

In macro expressions, following operator precedence rules apply. The order of operations can be changed by providing parantheses. The Expression Editor automatically fully parenthesizes any expression so that what operator precedence rules were used is obvious. If you type 5 == 2 + 3 * 4 to Expression Editor it will automatically parse and convert it to 5 == (2 + (3 * 4)).

Precedence	Category	Operators
1	Increment/Decrement	++	––
2	Unary	!	–	+
3	Product	*	/	%
4	Sum & Concatenation	+	–	&
5	Comparison	==	!=	<	<=	>	>=
6	Logical And	&&
7	Logical Or	\|\|
8	Ternary	?:
9	Assignment	=	+=	–=	*=	/=	%=	&&=	\|\|=	&=

Note: Assignments are evaluated right to left
