>>> (bitwise unsigned right shift)Syntax
expression1
>>>
expression2
Arguments
expression1
A number, string, or expression to be shifted right.
expression2
A number, string, or expression that converts to an integer from 0 to 31.
Description
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.
Player
Flash 5 or later.
Example
The following example converts -1 to a 32-bit integer and shifts it one 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 one 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
.
