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.

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.

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 operations like modulus, the general formula would be necessarily be quite complicated, I wouldn't even bother trying to recreate it.

May 20, 2017 · I agree with Martin, simply saying "use arithmetic expansion" doesn't answer the question "How to use bitwise operators in if statements?".

I tried to understand how if condition work with bitwise operators. A way to check if a number is even or odd can be done by: #include <iostream> #include <string> using namespace std;

Jun 26, 2013 · Bitwise operator performs logical AND operation on each pair of corresponding bits of operands. The result is a vector which width equals to maximal width of operands. Reduction operator performs logical AND operation between all the bits of a single vector. The result is a single bit boolean value.

Aug 8, 2015 · How can I implement division using bit-wise operators (not just division by powers of 2)? Describe it in detail.
