result |= expression

Parameters

Result

Description

Using this operator is equivalent to using the following statement:

result = result | expression

The |= operator looks at the value of the binary notation of result and expression , and performs a bitwise OR action. The results of this operation are as follows:

0101    (result)1100    (expression)----1101    (Output)

At any time, as long as one of the two expressions is 1, the result is 1. Otherwise, the bit of the result is 0.
