Skew binary number system must be the first non-zero least significant digit. In this case 15 is written canonically as 1000. Skew binary representations of the numbers from 0 to 15 are shown in following table: The advantage of skew binary is that each increment operation can be done with at most one carry operation. This exploits the fact that formula_3. Incrementing a skew binary number is done by setting the only two to a zero and incrementing the next digit from zero to one or one to two. When numbers are represented using a form of run-length encoding as linked lists of the
Compound File Binary Format Binary Format is a container, with little restriction on what can be stored within it. A CFBF file structure loosely resembles a FAT filesystem. The file is partitioned into "Sectors" which are chained together with a "File Allocation Table" (not to be mistaken with the file system of the same name) which contains chains of sectors related to each file, a "Directory" holds information for contained files with a Sector ID (SID) for the starting sector of a chain and so on. The CFBF file consists of a 512-Byte header record followed by a number of sectors whose size is
