Explanation of Bitwise NOT Operator - Stack Overflow
Bitwise works on the binary level, so 0 on binary would seen as 0000_0000, and (in two's complemented) -1 is 1111_1111, this not 0 flips all the bits to 1s, thus alters 0 into -1. But in an unsigned type (like C# uint) it'll be the max value possible.
boolean - What are bitwise operators? - Stack Overflow
In digital computer programming, a bitwise operation operates on one or more bit patterns or binary numerals at the level of their individual bits. It is a fast, primitive action directly supported by the processor, and is used to manipulate values for comparisons and calculations. operations: bitwise AND. bitwise OR. bitwise NOT. bitwise XOR ...
Bitwise assignment operators in C# - Stack Overflow
Nov 28, 2011 · C# AND assignment operator (&=) with bitwise enums. 0. Bitwise operation in C#. Hot Network Questions
What are bitwise shift (bit-shift) operators and how do they work?
The Bitwise operators are used to perform operations a bit-level or to manipulate bits in different ways. The bitwise operations are found to be much faster and are some times used to improve the efficiency of a program. Basically, Bitwise operators can be applied to the integer types: long, int, short, char and byte. Bitwise Shift Operators
Real world use cases of bitwise operators - Stack Overflow
Bitwise operators are useful for looping arrays which length is power of 2. As many people mentioned, bitwise operators are extremely useful and are used in Flags, Graphics, Networking, Encryption. Not only that, but they are extremely fast. My personal favorite use is to loop an array without conditionals.
Implementing if - else if using bitwise operators - Stack Overflow
Jun 2, 2013 · Assume that the value of test is 1 or 0. Here I can implement the following if statement using bitwise operators as below.
c - Replacing "==" with bitwise operators - Stack Overflow
Nov 12, 2010 · The C ! operator is really just shorthand for != 0, so using it seems very close to cheating :). Here's my take just using bitwise operations, assuming a 32-bit two's complement machine with arithmetic right shifts (technically, in C arithmetic right shifts are undefined, but every C compiler I've ever seen on a two's complement machine supports this correctly):
c++ - Performance wise, how fast are Bitwise Operators vs. Normal ...
Dec 5, 2013 · Bitwise operations are much faster. This is why the compiler will use bitwise operations for you. Actually, I think it will be faster to implement it as: ~i & 1 Similarly, if you look at the assembly code your compiler generates, you may see things like x ^= x instead of x=0. But (I hope) you are not going to use this in your C++ code.
Add two integers using only bitwise operators? - Stack Overflow
Nov 1, 2010 · Think about how addition happens bit by bit. Shift the values to get each bit of each operand in turn, then look at the four possible values for the two bits and work out what the result bit should be and whether there's a carry bit to worry about. Then see how the result and carry can be caculated using the bitwise ops.
Bitwise and in place of modulus operator - Stack Overflow
Jun 19, 2010 · With regards to bitwise optimization, only modulo powers of two can "easily" be done in bitwise arithmetics. Generally speaking, only modulo powers of base b can "easily" be done with base b representation of numbers. In base 10, for example, for non-negative N, N mod 10^k is just taking the least significant k digits. References
