Many non-integral values, such as decimal 0.2, have an infinite place-value representation in binary (.001100110011...) but have a finite place-value in binary-coded decimal (0.0010)[bcd]. Consequently a system based on binary-coded decimal representations of decimal fractions avoids errors representing and calculating such values.
Rounding at a decimal digit boundary is simpler in BCD. Addition and subtraction in decimal does not require rounding.

Why is BCD used in computers?
BCD is used for binary output on devices that only display decimal numbers.
Why was bcd code extended to ebcdic code?
The major problem with BCD code is that only 64 (2 to the power 6) different charactor can be represented in it. this is not sufficient for providing decimal numbers (10), lower case letters (26), and large number of other special characters (28+) Rajesh Rajput se.rajesh.rajput@gmail.com ...And EBCDIC was obsoleted by ASCII because EBCDIC did not use continuous coding (all the letters of the alphabet in increasing binary values), and because IBM made it difficult for others to use.
What is BCD?
Binary Coded Decimal. It's a modified form of binary. 10 8 4 2 1. When the count gets to 10 the tens column has a 1 in it. 20 10 8 4 2 1. The tens are also arranged in a binary format. It makes the format more compact.
What is non weighted code give you its example?
Weighted codes have there bits presented in weightage. Simply put weighted codes are codes used for arithmetic operation. And unweighted codes there are no values for the bits. Simply put they can not be used for calculations. Examples are 8421 (BCD) binary, hex, octal ETC. For the former And grey codes, excess-3 etc. For the later.
What type of chip is the 74ls48?
A 74 series BCD to 7-segment decoder, converting 4 bit binary values into signals to drive a common anode 7 segment display. Datasheet can be found here:http://www.datasheetcatalog.org/datasheets/70/375646_DS.pdf
What is the decimal binary code for 30?
Decimal 30 = binary 11110. The decimal binary code (BCD), however, is 11 0000.
Why is BCD code called a weighted code?
A: A Binary code represent a binary number 0.1.2.4.8. etc. that is why it is called a weighted number
What are the 4 an invalid BCD code?
BCD code isn't valid for these integers , 10 , 11 , 12 , 13 , 14 i.e if these integers ae converted to binary code they 'd be called wrong BCD
What is a 4 BCD code?
A 4 BCD code is a 4 decimal-digit BCD code, thus a 16 digit binary-code. You take the decimal number 3545. It's BCD code is 0011 0101 0100 0101 where every 4 bits represent a decimal digit.
What are different types of binary code?
BCD codes,gray code,error detecting code,ASCII character code,Excess 3 code
What are ASII and BCD how are they used?
ASCII (American Standard Code for Information Interchange) and BCD (Binary Coded Decimal) are standards for storing information in the binary sytem. ASCII is used for storing alphabetic, numeric, symbols, and control characters in 8-bit binary, and BCD is used for storing numbers 0-9 in 4-bit binary.
What is bcd to gray code converter?
A BCD to Gray code converter is a digital circuit that converts Binary Coded Decimal (BCD) input to Gray code output. Gray code is a binary numeral system where two consecutive values differ in only one bit. The converter is often used in digital systems where minimizing errors during digital-to-analog conversions is critical.
What is the difference between binary codes and bcd codes?
In BCD each digit of a decimal number is coded as a separate 4 bit binary number between 0 and 9.For example:Decimal 12 in BCD is shown as 0001 0010 (Binary 1 and Binary 2), in Binary it is 1100.
What is the difference between a BCD to decimal decoder and a BCD to 7-segment decoder?
A: A BCD code must be decoded to provide a seven digit output to the 7 bars display that is the only way to see the binary number visually.
Show the number 47 in BCD and ACSII?
In BCD it is 00100111 In Binary, which is what you mean, it is 101111
What is the Binary equivalent of the gray code 11100?
0101 0011 (2) = 53 (16) which in BCD means 53
Explain binary coded decimal?
Binary Coded Decimal (BCD) is a set of coding systems for storing decimal digits in binary code. There are several such codes, I will give examples of 3: straight BCD, XS3 BCD, and 2 of 5 BCD. Straight BCD uses the actual binary value of the decimal digit value: 0 = 0000 1 = 0001 2 = 0010 3 = 0011 4 = 0100 5 = 0101 6 = 0110 7 = 0111 8 = 1000 9 = 1001 XS3 BCD adds 3 to the binary value of the decimal digit value to make the code: 0 = 0011 1 = 0100 2 = 0101 3 = 0110 4 = 0111 5 = 1000 6 = 1001 7 = 1010 8 = 1011 9 = 1100 2 of 5 BCD uses a 5 bit code where only 2 bits can be on in a decimal digit's code: 0 = 00011 1 = 11000 2 = 10100 3 = 10010 4 = 10001 5 = 01100 6 = 01010 7 = 01001 8 = 00110 9 = 00101
