>>= Operator |
Language Reference
Version 1 |

Used to shift the bits of an expression to the right, preserving sign.

result>>=expressionThe

>>=operator syntax has these parts:

PartDescriptionresultAny variable. expressionAny expression.

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

result = result >> expression

The

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

var temp temp = -14 temp >>= 2

For information on when a run-time error is generated by the

>>=operator, see the Operator Behavior table.
