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, ...

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.

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 ...

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 ...
