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.

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 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.

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

Jan 17, 2011 · int bitwise_XOR(int a, int b) { return (a + b) - (a & b) - (a & b); } The reason this works is that we are doing a full add, which is equivalent to XOR when the sum for any given bit position is <= 1, and then we're correcting for the case where a carry is generated (1 + 1) by subtracting 2 * (a & b) .

Apr 18, 2011 · Consider what being "even" and "odd" means in "bit" terms. Since binary integer data is stored with bits indicating multiples of 2, the lowest-order bit will correspond to 2 0, which is of course 1, while all of the other bits will correspond to multiples of 2 (2 1 = 2, 2 2 = 4, etc.).

Jun 23, 2013 · The | operator is a bitwise "Or". The result is the bits that are turned on in either of the numbers. 1001 | 1100 = 1101, since only the second bit from the right is zero in both. There are also the ^ and ~ operators, that are bitwise "Xor" and bitwise "Not", respectively.

Jun 19, 2011 · The bitwise operators treat the bits inside an integer value as a tiny array of bits. Each of those bits is like a tiny bool value. When you use the bitwise exclusive or operator, one interpretation of what the operator does is: for each bit in the first value, toggle the bit if the corresponding bit in the second value is set

The bitwise "and" of these two statements is a little more nebulous: (the numeric value of the statement 'my car is red') & (the numeric value of the statement 'my car has wheels') => number. If python knows how to convert the statements to numeric values, then it will do so and compute the bitwise-and of the two values.
