Operators

Table 2 lists and describes all operators recognized by the After Effects scripting engine. Table 3 shows the precedence and associativity for all operators.

-	Unary negation or subtraction.
~	Bitwise NOT.
!	Logical NOT.
*	Multiply.
/	Divide.
%	Modulo division.
+	Add.
<<	Bitwise left shift.
>>	Bitwise right shift.
>>>	Unsigned bitwise right shift.
<	Less than.
