How开发者_运维百科 do I perform an unsigned right shift (>>> in Java) in C/C++?In C, to get an unsigned shift, you just do a shift on an unsigned type.
Are there any efficient bitwise operations I can do to get the number of set bits that an integer ends with? For example 1110 = 10112 would be two trailing 1 bits. 810 = 10002 would be 0 trailing 1 bi
I am attempting to reverse engineer an LZ1/LZ77 decompression algorithm.The length of an area of the decode buffer/window to be output is encoded in the file as a variable length integer.I\'ve read as
The Problem: I want to return all of the rows from the Primary Data table together with the Highest Priority Exception based on the currently assigned Priority in an Exception table.
Alright, so I have 4 integers I want to wrap in a long. The 4 integers all contains 3 values, positioned in the first 2 bytes:
I have this function in C# to convert a little endian byte array to an integer number: int LE2INT(byte[] data)
I want to write a function getColor() that allows me to extract parts of a hexadecimal number entered as a long
I\'m very confused about behaviour of PHP\'s left shift function. I\'m using it on two different machines (dev and hosting), and they are giving me different answers. I\'ve tracked it down to this cal
I have a bit counting method that I am trying to make as fast as possible. I want to try the algorithm below from Bit Twiddling Hacks, but I don\'t know C. What is \'type T\' and what is the python eq
