Zero-Fill Right Shift
Format: x >>> y
Arguments: (int) x, y Any integers
Returns: (int) The value of x with all bits
shifted right y places
Description: This operator converts x from a
floating-point number to a 32-bit integer, shifts all bits y
places to the right, and then returns the result as a
floating-point number.
The difference between Right Shift
and Zero-Fill Right Shift is in how the sign bit is
treated. With Right Shift, the
sign is preserved by keeping the most significant bit unchanged.
With Zero-Fill Right Shift, the most significant bit is
set to zero.
Examples: 16>>>3 = 2 (10000
>>> 3 = 00010)
12>>>2 = 3 (01100
>>> 2 = 00011)
-12>>>2 =
1073741821 (sign is not preserved)
