Used to perform a bitwise AND on an expression.
result &= expression
The &= operator syntax has these parts:
Part Description result Any variable. expression Any expression.
Using this operator is exactly the same as specifying:result = result & expression
The &= operator looks at the binary representation of the values of result and expression and does a bitwise AND operation on them. The output of this operation behaves like this:0101 (result) 1100 (expression) ---- 0100 (output)
Any time both of the expressions have a 1 in a digit, the result has a 1 in that digit. Otherwise, the result has a 0 in that digit.
For information on when a run-time error is generated by the &= operator, see the Operator Behavior table.
