bitwise or

Summary

Performs a bitwise OR on two expressions.

Syntax

result = expression1 | expression2

result

Any variable.

expression1

Any expression.

expression2

Any expression.

Examples

See Remarks.

var x;
x = 5 | 12;
// result: x = 13

Remarks

The | operator looks at the binary representation of the values of two expressions and does a bitwise OR operation on them. 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.
