They provide only the >> operator, and the right-shifting behavior is implementation defined for signed types. If you want Foo + Foo to return a Foo and Bar + Bar to return a Bar, you will need to define one operator on each class.

(x |= y) is equivalent to (x = x | y) The Bitwise OR operator (|) is a binary operator which takes two bit patterns of equal length and performs the logical OR operation on each pair of corresponding bits. These values are known as Boolean values, and you will learn more about them in the Booleans and chapter. C# Math .Kftcvan - 중개보수 현금영수증 발급 방법 간단 정리
