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, ...

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 Part 1 of this two-part binary coded decimal (BCD) extravaganza, we introduced a bunch of bodacious concepts, including the binary (base-2) number system, binary logic, binary computers, and bits, ...

HERE’S A C/C++ PROGRAM that converts decimal numbers ranging from 0 to 99,999 to binary and binary coded decimal (BCD) formats. Using a simple algorithm in conjunction with pointer arithmetic and ...

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.

A rudimentary understanding of digital logic and simple integrated circuits is critical if you’re ever going to pull off some really gnarly hacks. [Daniel] put together an explanation about the use of ...

We observe that only ten of the sixteen (2 4) possible combinations are used in BCD; the remaining six combinations 1010, 1011, 1100, 1101, 1110, and 1111 are invalid in BCD. The designations A ...

What is Extended Binary Coded Decimal Interchange Code (EBCDIC)? Extended Binary Coded Decimal Interchange Code (EBCDIC) is an eight-bit encoding scheme that standardizes how alphanumeric characters, ...

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 ...

Here's a C/C++ program that converts decimal numbers ranging from 0 to 99,999 to binary and BCD formats. Using a simple algorithm in conjunction with pointer ...
