Binary number a separate "subtract" operation. Using two's complement notation subtraction can be summarized by the following formula: A − B = A + not B + 1 Multiplication in binary is similar to its decimal counterpart. Two numbers and can be multiplied by partial products: for each digit in , the product of that digit in is calculated and written on a new line, shifted leftward so that its rightmost digit lines up with the digit in that was used. The sum of all these partial products gives the final result. Since there are only two digits in binary, there are
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
