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.

117 Bitwise operations, including bit shift, are fundamental to low-level hardware or embedded programming. If you read a specification for a device or even some binary file formats, you will …

These are the bitwise operators, all supported in JavaScript: op1 & op2 -- The AND operator compares two bits and generates a result of 1 if both bits are 1; otherwise, it returns 0.

Aug 7, 2010 · Here is a quote from the book: The Bitwise AND Operator Bitwise ANDing is frequently used for masking operations. That is, this operator can be used easily to set specific …

1 Using bitwise_and, bitwise_or, and bitwise_not you can modify any bit configurations to another bit configurations (i.e. these set of operators are "functionally complete"). However, for …

Nov 17, 2009 · Bitwise operations in programming languages play a fundamental role when dealing with a lot of applications. Almost all low-level computing must be done using this kind …

What are some real world use cases of the following bitwise operators? AND XOR NOT OR Left/Right shift

Dec 5, 2013 · C operators are meant to map pretty much directly to assembly, and there is very much a difference between, e.g., a bitwise AND and modulo or division. The only reason they …

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 …
