Bitwise OR Operator (|)
Performs a bitwise OR on two expressions.
expression1 | expression2
Arguments
expression1
Any numeric expression.expression2
Any numeric expression.
Remarks
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.
