Web基於評論，您的實際問題似乎是“為什么 c# 設計師決定以這種方式定義它，而不是其他一些或更好但仍堅持類似於 c/c++ 的未定義行為”，這實際上是基於意見的（除非有一些官方設計文檔）存在保存了特定的討論和決定）： WebC# provides 4 bitwise and 2 bit shift operators. Bitwise and bit shift operators are used to perform bit level operations on integer (int, long, etc) and boolean data. These operators are not commonly used in real life situations. If you are interested to explore more, visit practical applications of bitwise operations.

Say you want to hold the number 1.23 (and bit-shift it later). You would store 123 in an int, and every time you accessed the variable you would divide the value by 100: Code: ? 1 2 3 int i = 123; i = i << 3; printf("%f", i/100.0); I hope this helps. 05-24-2005 #3 north herts council tax online
