Unsigned right shift operator (>>>) shifts the bit of the expression right without retaining the symbol. Result = expression1 >>> expression2 >>> the operator shifts the bits of expression1 to the right of the bits specified by expression2.
After the right shift, the left blank space is filled with zero. Removed from the right side is discarded, for example, M =-3> 2-3 is 1111 1101 at this time M = 0011 1111 and> for the unsigned number is the same as the above if it is signed
Depends on the operating system used.
Divided into logical right shift, that is, add 0 at the highest bit
The right shift of arithmetic is to add 1 in the highest bit.
