Editor's Note: This is the first article in a two-part series on decimal representations and decimal arithmetic in general, and on Binary Coded Decimal (BCD) in particular. In this first installment, ...

binary-coded decimal (BCD) is a class of binary encodings of decimal numbers where each digit is represented by a fixed number of bits, usually four or eight. Both Zoned Decimal and Packed Decimal ...

I'm stumped on this.<BR><BR>I need to create a data file that some back end mainframe process can load. There is a specification file that is Cobol, and it specifies that most fields that deal with ...

Binary codes are codes which are characterized in binary system with alteration from the original ones. The two types of binary codes are the Weighted Binary Systems and Non Weighted Codes. Weighted ...

Abstract: A parallel decimal multiplier is proposed in this paper to improve performance by mainly exploiting the properties of three different binary coded decimal (BCD) codes, namely the redundant ...

When anyone is first introduced to the topic of digital computers, they are almost invariably told that these machines are based on binary (base-2) logic and the binary number system, where “binary” ...

In the computer, all data are represented as binary digits (bits), and eight binary digits make up one byte. For example, the upper case letter A is 0101001. Numbers however can take several forms.

While desktop computers have tons of computing power and storage, some small CPUs don’t have a lot of space to store things. What’s more is some CPUs don’t do multiplication and division very well.
