What is the importance of BCD?
The main advantage of the Binary Coded Decimal system is that it is a fast and efficient system to convert the decimal numbers into binary numbers as compared to the pure binary system. But the BCD code is wasteful as many of the 4-bit states (10-to-16) are not used but decimal displays have important applications.
What is the most important operation in binary coded decimal BCD arithmetic?

What is binary coded decimal BCD and how is it used in automation?
Binary-coded decimal (BCD) is a class of binary encodings of decimal numbers where each decimal is represented by a fixed number of bits, usually four or eight, which goes against the way humans compute data. This disconnect can cause problems for programmable logic controller (PLC) users. Computers hate decimals.
What is BCD value?
In computing and electronic systems, binary-coded decimal (BCD) is a class of binary encodings of decimal numbers where each digit is represented by a fixed number of bits, usually four or eight.
Who uses binary code?
The American Standard Code for Information Interchange (ASCII), uses a 7-bit binary code to represent text and other characters within computers, communications equipment, and other devices. Each letter or symbol is assigned a number from 0 to 127.
How do you convert binary into decimal?
How to convert binary to decimal. The decimal number is equal to the sum of binary digits (dn) times their power of 2 (2n): decimal = d0×20 + d1×21 + d2×22 +
How do you calculate a binary number?
To calculate the number value of a binary number, add up the value for each position of all the 1s in the eight character number. The number 01000001, for example, is converted to 64 + 1 or 65.
What is BCD mean?
Binary coded decimal (BCD) is a system of writing numerals that assigns a four-digit binary code to each digit 0 through 9 in a decimal (base-10) numeral.
