Bitwise OR: The corresponding bit of the result is 1 if at least one input number has a 1 on this bit otherwise, it is 0.Bitwise AND: The corresponding bit of the result is 1 if both input numbers have a 1 on this bit otherwise, it is 0.The bitwise calculator can perform 3 different bitwise operations: bitwise AND, bitwise OR, and bitwise XOR: We have two input integers in binary format, and the two binary numbers are compared bit by bit, position by position, from the first to the last. You can check out our decimal to octal converter and decimal to hexadecimal converter to learn more about these number systems.Ī bitwise operation is executed on a binary number, which can also be seen as a string of bits. There are other popular numeral systems besides the binary and decimal ones, namely the octal system based on the number 8 and the hexadecimal or 16-base system. It describes the same method used in this application to convert negative numbers from the decimal to the binary system: the signed two's complement representation. The binary converter provides a closer inside into the world of the binary system. ![]() For example, the binary number 101 equals 1×2² + 0×2¹ + 1×2⁰, which equals 5 in the decimal system. So every digit of a number corresponds to a power of 2. For example, the number 123 can be expressed as 1×10² + 2×10¹ + 3×10⁰ (scientific notation). Every digit of a number corresponds to a power of the base 10. The decimal system, also known as the base-10 system, uses the digits 1 to 9.So let's compare binary numbers made from bits of information to our habitual decimal system: ![]() Most of us are not used to thinking in the way of bits when talking about numerical information. ![]() For example, one byte is a succession of 8 bits, equaling 2^8 logical states. Since a single bit can only encode a very limited amount of information, bits are lined up to represent larger amounts of data. Alternatively, the logic pairs true/false, on/off, or yes/no can be used. Information is encoded in a logical state, which can only have two different values: 1 or 0. A bit is the smallest unit of information used in digital communication and electronics.
