Web5 Answers. You're correct; it is used to truncate the value. The reason >> works is because it operates only on 32-bit integers, so the value is truncated. (It's also commonly used in cases like these instead of Math.floor because bitwise operators have a low operator precedence, so you can avoid a mess of parentheses.)

WebDec 9, 2011 · If you keep bits in a BitArray you can store a pointer to the start index in one integer. Shifting would be - adding one element at the end and moving the start pointer by one. This would work in O (1).

WebMay 5, 2009 · Second type cast is technically redundant. You could shorten it up by writing (long)left << 32 (uint)right. this shifts the first int left by 32 bits (the length of an int), then ors in the second int, so you end up with the two ints concatentated together in a long. Be careful with the sign bit. WebIs there any way to do this in C# that would enable me to access the bits using the struct dereferencing dot operator?
