>>> (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.
