Operators

Binary Operators

Binary operators in Zeen cover arithmetic, comparison, logical and bitwise operations.

Table of supported binary operators:

Operator	Name	Description
+	Add	Addition operator
-	Sub	Subtraction operator
*	Mul	Multiplication operator
/	Div	Division operator (division by 0 panics)
%	Mod	Modulus operator (division by 0 panics)
==	Eq	Equality comparison
!=	Ne	Negated equality comparison
<	Lt	true if left less than right
>	Gt	true if left greater than right
<=	Le	true if left less or equals right
>=	Ge	true if left greater or equals right
&&	LogicalAnd	true if both sides are true
||	LogicalOr	true if either side is true
&	BitAnd	Bits level AND operation
|	BitOr	Bits level OR operation
^	BitXor	Bits level XOR operation
<<	BitShl	Shift left by the number of bits given by the right operand
>>	BitShr	Shift right by the number of bits given by the right operand

&& and || always evaluate both sides (no short-circuit).

Overloading

Overloadable operators map to interfaces (< > <= >= && || are not):

Operator	Interface	Method
+	Add	add
-	Sub	sub
*	Mul	mul
/	Div	div
%	Mod	mod
== !=	Eq	eq
&	BitAnd	bit_and
|	BitOr	bit_or
^	BitXor	bit_xor
<<	BitShl	bit_shl
>>	BitShr	bit_shr
-EXPR	Neg	neg
!EXPR	Not	not
~EXPR	BitNot	bit_not
*EXPR	Deref	deref

Unary Operations

Unary operations involve single operand instruction.

Table of supported unary operators:

Operator	Name	Description
-EXPR	Neg	Negates operand
!EXPR	Not	Boolean NOT operation
~EXPR	BitNot	Bitwise NOT operation
*EXPR	Deref	Dereference operation (for pointers)
&EXPR	AddrOf	Take address of expression (returns *T type)
