7.4.7 Bitwise AND Operator (&)

Used to perform a bitwise AND on two expressions.
 

Syntax

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.
