result

Any variable.

expression

Any expression.

Using the >>= operator is exactly the same as specifying:

 	Copy Code
result = result >> expression

The >>= operator shifts the bits of result right by the number of bits specified in expression. The sign bit of result is used to fill the digits from the left. Digits shifted off the right are discarded. For example, after the following code is evaluated, temp has a value of -4: 14 (11110010 in binary) shifted right two bits equals -4 (11111100 in binary).

 	Copy Code
var temp temp = -14 temp >>= 2
