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.
Understanding the bitwise AND Operator - Stack Overflow
Aug 7, 2010 · The Bitwise AND Operator. Bitwise ANDing is frequently used for masking operations. That is, this operator can be used easily to set specific bits of a data item to 0. For example, the statement. w3 = w1 & 3; assigns to w3 the value of …
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.
Bitwise assignment operators in C# - Stack Overflow
Nov 28, 2011 · Need help understanding usage of bitwise operators. 1. C# Bitwise Operator With Ints. 0.
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.
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 ...
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.
Can someone explain ARM bitwise operations to me?
Jan 28, 2012 · Now we get to the BIC instruction. Which stands for bitwise clear, which hopefully will make sense in a bit. Bic on the arm is a anded with not b. Not is another truth table, but only one input and one output. NOT. a c 0 1 1 0 With only one input we have only two choices 0 and 1, 1 is true 0 is false. NOT means if not a then c is true.
c - Replacing "==" with bitwise operators - Stack Overflow
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):
Multiplication of two integers using bitwise operators
Feb 12, 2016 · The Wikipedia entry on bitwise operator applications has some pseudo code, but it uses the addition operator as well as bitwise operators. – JonMR Commented Dec 16, 2010 at 1:05
