BCD is a decimal number. BCD is one specific way to store decimal numbers in computer memory.
1111 can't be used for Binary Coded Decimal (BCD) because 1111=15 which is made of 2 digits 1 and 5. In BCD a 4-digit binary number is used for every decimal digit. ex. 1111 is incorrect 1 = 0001 5 = 0101 Answer: 0001 0101
To represent an eight-digit decimal number in Binary-Coded Decimal (BCD), each decimal digit is encoded using 4 bits. Since there are 8 digits in the number, the total number of bits required is 8 digits × 4 bits/digit = 32 bits. Therefore, 32 bits are needed to represent an eight-digit decimal number in BCD.
In Binary-Coded Decimal (BCD) addition, the digit 6 plays a crucial role as a threshold for determining whether a correction is needed after standard binary addition. BCD represents decimal digits using four bits, and if the sum of two BCD digits exceeds 9 (which is 1001 in binary), a correction of 6 (0110 in binary) is added to bring the result back into valid BCD range. This adjustment ensures that the resulting sum correctly represents decimal values. Thus, 6 is effectively used to convert invalid BCD results back into valid representations.
BCD, or Binary Coded Decimal, is called 8421 code because it represents each decimal digit using a 4-bit binary number, where the weights of the bits correspond to the binary values of 8, 4, 2, and 1. In this encoding system, the four bits are assigned values based on their position, allowing for the unique representation of decimal digits 0 through 9. The name "8421" reflects the specific weights assigned to each bit, facilitating easy conversion between decimal and binary formats.
BCD, which stands for Binary Coded Decimal. 4 bits are used to code each decimal digit. So we have 0000 for zero, up to 0111 for seven, then 1000 for eight and 1001 for nine. The others {ten through fifteen} are not used, as those numbers are formed from additional decimal digits. So if you wanted to form twelve, in BCD it is 0001 0010, for 12{base ten}
BCD of 862 is 100001100010
41 in decimal is 0100 0001 in BCD (this is 8 bits not 6 bits)41 in decimal is 101001 in binary (this is 6 bits, but binary not BCD)There is no 6 bit BCD representation of the decimal number 41!
BCD is used for binary output on devices that only display decimal numbers.

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.

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.
BCD (Binary Coded Decimal) output can be generated using decimal-to-BCD conversion algorithms. One common method involves dividing the decimal number by 10 and storing the remainder as the Binary Coded Decimal digit. This process is repeated until all decimal digits are converted into BCD form. Alternatively, some microcontrollers have built-in instructions to directly convert decimal numbers to BCD format.
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.
The decimal number 10, represented in BCD is 0001 0000. If, instead, you mean that you have 10 in BCD and want to know what that means, that is equivalent to 0000 0010 and would be 2 in decimal.
It is 0001 0110 0011.
