Bitwise OR Operator (|)

Performs a bitwise OR on two expressions.

expression1 | expression2


Any numeric expression.


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 OR 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)
1101   (result)

Any time either of the expressions has a 1 in a digit, the result will have a 1 in that digit. Otherwise, the result will have a 0 in that digit.
