* Binary Coded Decimal*. In BCD, numbers are represented in a decimal form, however each decimal digit is encoded using a four bit binary number. For example: The decimal number 160 would be represented in BCD as follows: 160 = 0001 0110 0000. 1 6 0. Decimal Number System . In decimal number system there only ten (10) digits from 0 to 9 In computing and electronic systems, a binary-coded decimal (BCD) is a digital encoding method for decimal numbers in which each digit is represented by its own binary sequence. BCD is different from converting a decimal number to binary. For example, 45, when converted to binary, is 101101, and when represented in BCD is 01000101

As discussed in the above section, while converting demultiplexer to decoder, the select lines of demultiplexers become the inputs of decoder, which is the select lines or control line S3, S2, S1, and S0 will become the input os BCD to the decimal. Binary coded decimal 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. The four-bit BCD code for any particular single base-10 digit is its representation in binary notation, as follows: 0 = 0000. 1 = 0001. 2 = 0010. Numbers larger than 9, having two or more digits in the decimal system, are expressed digit by digit in binary coded decimal. For example, the BCD rendition of the base-10 number 1895 is 0001 1000 1001.

Since the upper nibble is always empty (since 9, the maximum, is 1001) - let's use only one nibble for each decimal digit. And this was called packed BCD. In packed BCD, our 0.8 becomes 0.1000, and, for example, 6.75 become 0110.01110101 How to Calculate Hexadecimal to Decimal. Hex is a base 16 number and decimal is a base 10 number. We need to know the decimal equivalent of every hex number digit. See below of the page to check the hex to decimal chart. Here are the steps to convert hex to decimal: Get the decimal equivalent of hex from table 1000111 2 = 0100 0111 BCD = 47 10. 10100111000.101 2 = 0101 0011 0001.1010 BCD = 538.625 10. The conversion of BCD-to-decimal or decimal-to-BCD is a relatively straight forward task but we need to remember that BCD numbers are decimal numbers and not binary numbers, even though they are represented using bits Binary Coded Decimal. In BCD, numbers are represented in a decimal form, however each decimal digit is encoded using a four bit binary number. For example: The decimal number 160 would be represented in BCD as follows: 160 = 0001 0110 0000. 1 6 0.

BCD or Binary Coded Decimal is that number system or code which has the binary numbers or digits to represent a decimal number. A decimal number contains 10 digits (0-9). Now the equivalent binary numbers can be found out of these 10 decimal numbers. In case of BCD the binary number formed by four binary digits, will be the equivalent code for the given decimal digits The idea is to extract the digits of a given binary number starting from right most digit and keep a variable dec_value. At the time of extracting digits from the binary number, multiply the digit with the proper base (Power of 2) and add it to the variable dec_value

Converting between decimal and binary-coded-decimal (BCD) Posted on 2015/04/13 by admin When tinkering with Arduinos, you're going to come across quite a number of components that provide data out - or require data in - Binary Coded Decimal (BCD for short)

The binary-coded decimal scheme described in this article is the most common encoding, but there are many others. The method here can be referred to as Simple Binary-Coded Decimal (SBCD) or BCD 8421. The following table represents decimal digits from 0 to 9 in various BCD systems ** A regular decimal number is the sum of the digits multiplied with power of 10**. 137 in base 10 is equal to each digit multiplied with its corresponding power of 10: 137 10 = 1×10 2 +3×10 1 +7×10 0 = 100+30+7. Hex numbers are read the same way, but each digit counts power of 16 instead of power of 10 The most significant digits of the output truncate away. For example, if the binary range is set to 4 bits and the **BCD** range is set to 1 digit, then a binary input of 1100 (**decimal** 12) will result in an output of 0010 (**decimal** 2) The 74HC42 is a one of ten BCD to decimal decoder. It accepts four BCD inputs (0A to 3A) and provides ten mutually exclusive outputs (0Y to 9Y). The logic design ensures that all outputs are HIGH when binary codes greater than nine are applied to the inputs So the 8421 BCD code for the decimal number 6 10 is 0110 8421.Check this from Table 1.6.1. For numbers greater than 9 the system is extended by using a second block of 4 bits to represent tens and a third block to represent hundreds etc
