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” ...

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 ...

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 ...

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, ...

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.

Decimal arithmetic is indispensable in applications where precision is paramount, such as in financial, commercial and scientific domains. The inherent challenges of decimal computation, particularly ...

Microcontroller firmware usuallydeals with hexadecimal code. Yousometimes need to display the contentof registers, which requires a hexadecimal-to-BCD (binary-coded-decimal)-code conversion. The ...
