What is a Binary-Coded Decimal (BCD)?

Definition and meaning of Binary-Coded Decimal

A Binary-Coded Decimal (BCD) is a sort of binary representation for decimal values wherein every digit is represented by way of a fixed quantity of binary bits, typically among 4 and 8.

The norm is four bits, which efficaciously represent decimal values zero to nine. This writing layout gadget is used because there's no restriction to the scale of quite a number. Four bits can truly be delivered as any other decimal digit, as opposed to actual binary representation, which is confined to the same old powers of two, including sixteen, 32 or sixty four bits.

What Does Binary-Coded Decimal Mean?

Binary-coded decimals are an easy manner to symbolize decimal values, as each digit is represented with the aid of its Personal 4-bit binary sequence which handiest has 10 specific combinations. By assessment, converting real binary illustration to decimal requires mathematics operations like multiplication and addition.

It is less complicated for conversion to decimal digits for display or printing, however the ensuing Circuit required to put in force this Device is Greater complicated.For Instance, the Binary Coded decimal "1001 0101 0110," which has 3 corporations of 4 bits, way there are 3 decimal digits. In order, from left to proper, the resulting decimal price is 956.

The following are the four-bit binary illustration of decimal values:

0 = 0000 1 = 0001 2 = 0010 three = 0011 four = 0100 five = 0101 6 = 0110 7 = 0111 8 = 1000 9 = 1001

What does BCD stand for?

When we refer to BCD as an acronym of Binary-Coded Decimal, we mean that BCD is formed by taking the initial letters of each significant word in Binary-Coded Decimal. This process condenses the original phrase into a shorter, more manageable form while retaining its essential meaning. According to this definition, BCD stands for Binary-Coded Decimal.
