BCD (binary coded decimal) is a system for converting ordinary decimal digits (the numbers 0-9) into 4-bit binary numbers. In BCD, each digit of a decimal number is coded separately as a 4-bit word (sometimes called a "nibble," since 8-bit words are...

In computing and electronic systems, binary-coded decimal (BCD) is an encoding for decimal numbers in which each digit is represented by its own binary sequence. Its main virtue is that it allows easy conversion to decimal digits for printing or display...

The computer program HEXBCD, an 8051 muC subroutine, was presented. The program transforms a 16-bit HEX number in internal RAM locations 33 and 34H into its BCD equivalent and puts the results in scratchpad registers, namely R1, R2 and R3. A 16-bit conversion is...
