Bitwise AND Operator (&)

Performs a bitwise AND on two expressions.

expression1 & expression2

expression1

Any numeric expression.

expression2

Any numeric expression.

The & operator coerces the arguments to matching data types. Then the & operator looks at the binary representation of the values of two expressions and does a bitwise AND operation on them. The data types of the arguments determine the data type returned by this operator.

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.
