Operators 113
= (assignment) Assigns the value of expression2 (the parameter on
the right) to the variable, array element, or property in
expression1.
& (bitwise AND) Converts expression1 and expression2 to 32-bit
unsigned integers, and performs a Boolean AND
operation on each bit of the integer parameters.
&= (bitwise AND assignment) Assigns expression1 the value of expression1&
expression2.
<< (bitwise left shift) Converts expression1 and expression2 to 32-bit
integers, and shifts all the bits in expression1 to the
left by the number of places specified by the integer
resulting from the conversion of expression2.
<<= (bitwise left shift and
assignment)
This operator performs a bitwise left shift (<<=) operation
and stores the contents as a result in expression1.
~ (bitwise NOT) Also known as the one's complement operator or the
bitwise complement operator.
| (bitwise OR) Converts expression1 and expression2 to 32-bit
unsigned integers, and returns a 1 in each bit position
where the corresponding bits of either expression1
or expression2 are 1.
|= (bitwise OR assignment) Assigns expression1 the value of expression1 |
expression2.
>> (bitwise right shift) Converts expression1 and expression2 to 32-bit
integers, and shifts all the bits in expression1 to the
right by the number of places specified by the integer
that results from the conversion of expression2.
>>= (bitwise right shift and
assignment)
This operator performs a bitwise right-shift operation
and stores the contents as a result in expression1.
>>> (bitwise unsigned right
shift)
The same as the bitwise right shift (>> ) operator except
that it does not preserve the sign of the original
expression because the bits on the left are always
filled with 0. Floating-point numbers are converted to
integers by discarding any digits after the decimal
point.
>>>= (bitwise unsigned right
shift and assignment)
Performs an unsigned bitwise right-shift operation and
stores the contents as a result in expression1.
