	/	Real number In addition	integers, real numbers	Real	X/2
	Div	Integer except	Integer	Integer	Total Div unitsize
	MoD	Take the mold	Integer	Integer	Y MoD 6
	+ (one yuan)	Symbolic equivalents	integers, real numbers	integers, real numbers	+7
	-(one Yuan)	Symbol opposite	integers, real numbers	integers, real numbers	-X
Boolean operator	Not	Negative	Boolean type	Boolean	Not (C in MySet)
	and	And	Boolean type	Boolean	Done and (Total > 0)
	Or	Or	Boolean type	Boolean	A or B
	Xor	XOR or	Boolean type	Boolean	A XOR B
Logical (bitwise) operator	Not	Bitwise negation	Integer	Integer	Not X
	and	Bitwise-AND	Integer	Integer	X and Y
	Or	Bitwise OR	Integer	Integer	X or Y
	Xor	Bitwise XOR OR	Integer	Integer	X XOR Y
	Shl	Bitwise LEFT Shift	Integer	Integer	X SHL 2
	Shr	Bitwise RIGHT SHIFT	Integer	Integer	Y SHR I
String operators	+	Connection	string, compressed string, character	String	S + '. '
Pointer operators	+	Pointer Plus	Character pointer, integer	Character pointer	P + I
	-	Pointer minus	Character pointer, integer	Character pointer, integer	P-q
	^	Pointer dismiss reference	Pointer	Base type of pointer	p^
	=	Equal	Pointer	Boolean	P = Q
	<>	Range	Pointer	Boolean	P <> Q
Set operators	+	and set	Collection	Collection	Set1 + Set2
	-	Subtraction	Collection	Collection	S–t
	*	Intersection	Collection	Collection	S * T
	<=	Subset	Collection	Boolean	Q <= MySet
	>=	Hyper-Set	Collection	Boolean	S1 >= S2
	=	Equal	Collection	Boolean	S2 = MySet
	<>	Range	Collection	Boolean	MySet <> S1
	Inch	Members	Ordinal, set	Boolean	A in Set1
Relational operators	=	Equal	Simple types, classes, class references, interfaces, strings, compressed strings	Boolean	I = Max
	<>	Range	Simple types, classes, class references, interfaces, strings, compressed strings	Boolean	X <> Y
	<	Less than	Simple type, string, compressed string, PChar	Boolean	X < Y
	>	Greater than	Simple type, string, compressed string, PChar	Boolean	Len > 0
	<=	Less than or equal to	Simple type, string, compressed string, PChar	Boolean	Cnt <= 1
	>=	Greater than or equal to	Simple type, string, compressed string, PChar	Boolean	I >= 1
Class operator	As	Transformation	Instances of classes and classes
	Is	Judge
	=		Relational operators = and <> are also used for classes
	<>
Address (@) operator	@X	If x is a variable, then @x returns the address of X.  When the compilation indicator {$T-} is valid, @x is the pointer type; When the compiler indicates {$T +} state, @x is the ^t type, where T is the type of x.
	@F	If f is a routine (function or procedure), then @f returns the entry point of F, and the type of @f is always pointer.
	Methods in the @ class	When @ is applied to a method defined in a class, the method identifier must be qualified by the name of the class. For example: @TMyClass. dosomething

Delphi operators and Precedence

Monocular operator (highest priority)
@	Takes the address of a variable or function (returns a pointer)
Not	logical inversion or bitwise inversion
Multiplication and bitwise operators
*	Multiply or set intersection
/	Divide floating point
Div	Dividing integers
MoD	Modulo (the remainder of dividing integers)
As	Program run stage type conversion (Rtti operator)
and	Logical OR Bitwise summation
Shl	Bitwise LEFT Shift
Shr	Bitwise RIGHT SHIFT
Add and Subtract operators
+	Add, set merge set, string join, or pointer increment an offset
-	Subtract, set difference set, or pointer reduce an offset
Or	Logical OR bitwise OR operation
Xor	Logical OR bitwise XOR OR operation
Relationship and comparison operators (lowest priority)
=	Judging if they are equal
<>	Judging if they are not equal
<	Judging if it is less than
>	Judging if it is greater than
<=	Determines whether it is less than or equal to, or whether it is a subset of a collection
>=	Determines whether the parent set is greater than or equal to, or is a collection
Inch	Determines whether a collection member
Is	Determine if an object is type compatible (another rtti operator)
