| 2. 5. 18. >>> (Shift Right Zero Fill) |
|
|
The shift right zero fill operator looks at the integer to the left of the operator as a 32-bit binary number. |
All the bits in this number are shifted to the right by the number of positions specified by the integer to the right of the operator. |
As the bits are shifted to the right, zeros are filled in on the left, regardless of the sign of the original integer. |
The extra bits on the right are lost. |
The 32-bit binary result of this shifting operation is converted to an integer value and returned from the shift right zero fill operation. |
