Binary To Decimal Algorithm
In computing and electronic systems, binary-coded decimal (BCD) is a class of binary encodings of decimal numbers where each decimal digit is represented by a fixed number of bits, normally four or eight. In byte-oriented systems (i.e. most modern computers), the term unpacked BCD normally imply a full byte for each digit (often including a sign), whereas packed BCD typically encodes two decimal digits within a individual byte by take advantage of the fact that four bits are enough to represent the range 0 to 9.
