JavaScript tutorial:
>>>= operator


The (>>>=) operator is used to make an unsigned right shift of the bits in a variable.


result >>>= expression

The >>>= operator syntax has these parts:




Any variable.


Any expression.


Using the >>>= operator is exactly the same as doing the following:

result = result >>> expression

The >>>= operator shifts the bits of result right by the number of bits specified in expression. Zeroes are filled in from the left. Digits shifted off the right are discarded. For example:

temp = -14
temp >>>= 2

To run the code above, paste it into JavaScript Editor, and click the Execute button.

The variable temp has a value of 1073741820 as -14 (11111111 11111111 11111111 11110010 in binary) shifted right two bits equals 1073741820 (00111111 11111111 11111111 11111100 in binary).

For information on when a run-time error is generated by the >>>= operator, see the Operator Behavior table.
