>>>expression2
expression1
A number or expression to be shifted right.
expression2
A number or expression that converts to an integer between 0 and 31.
Nothing.
Operator (bitwise); 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.
The following example converts -1 to a 32-bit integer and shifts it 1 bit to the right.
x = -1 >>> 1
The result of the above operation is as follows:
x = 2147483647
This is because -1 decimal is 11111111111111111111111111111111 binary (thirty-two 1's), and when you shift right (unsigned) by 1 bit, the least significant (rightmost) bit is discarded, and the most significant (leftmost) bit is filled with a 0. The result is 01111111111111111111111111111111 binary, which represents the 32-bit integer 2147483647.
