Bitwise AND Operator (&)

Performs a bitwise AND on two expressions.

result = expression1 & expression2

Arguments

result
Any variable.
expression1
Any expression.
expression2
Any expression.

Remarks

The & operator looks at the binary representation of the values of two expressions and does a bitwise AND operation on them. The result of this operation behaves as follows:

0101   (expression1)
1100   (expression2)
----
0100   (result)

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.
