Why do we add 6 in BCD?

Because each hexadecimal digit has 16 different values and BCD has only 10. ... Similarly, in BCD math, when the result of the addition is larger than 9 you add 6 to skip the 6 remaining "invalid" values and carry to the next digit.

What is the BCD value of 1010?

This means that although 16 numbers (2⁴) can be represented using four binary digits, in the BCD numbering system the six binary code combinations of: 1010 (decimal 10), 1011 (decimal 11), 1100 (decimal 12), 1101 (decimal 13), 1110 (decimal 14), and 1111 (decimal 15) are classed as forbidden numbers and can not be used ...

What is the BCD of 37?

For example: 37 in decimal becomes 0x37 in BCD!

What is the BCD code of 89?

Therefore, the binary equivalent of decimal number 89 is 1011001.

(Binary Coded Decimal) The storage of numbers in which each decimal digit is converted into a binary number and stored in a single 8-bit byte. For example, a 12-digit decimal number would be represented as 12 bytes. BCD uses more storage for numbers than binary encoding (see below).
