Binary 00111000
Convert to Decimal 56
Convert to BCD by using groups of four binary numbers for each digit
5 6
0101 0110
All possible 2-bit numbers ... 0, 1, 2, and 3 ... are the same in BCD and binary. No conversion is required.
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.
In BCD it is 00100111 In Binary, which is what you mean, it is 101111
Write a program to convert a 2-digit BCD number into hexadecimal
BCD is used for binary output on devices that only display decimal numbers.
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!
Binary coded decimal (BCD) is easier to convert between displayed or printed form than is pure binary.
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.
WRITE A PROGRAM TO CONVERT A 2-DIGIT bcd NUMBER INTO HEXADECIMAL
A: A Binary code represent a binary number 0.1.2.4.8. etc. that is why it is called a weighted number
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.
