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.

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 …

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 …

The result of the &, | and ^ operators is defined in terms of the bitwise representation of the values. Three possibilities are allowed for the representation of negative numbers in C: two's …

Aug 24, 2008 · Using bitwise operations for bool helps save unnecessary branch prediction logic by the processor, resulting from a 'cmp' instruction brought in by logical operations.

Jun 21, 2013 · 1 Is there any functional difference between logical and bitwise operators in the following case? Yes, there is (lazy eval as others have pointed out). Any reason to support one …
