A Decimal-to-BCD Converter is a tool that converts decimal numbers to binary-coded decimal (BCD) format. BCD is a binary representation of decimal numbers where each decimal digit is represented by a group of four bits.

**Here’s how you can convert a decimal number to BCD:**

- Write the decimal number in binary format.
- If the number of bits is less than 8, add leading zeros to make it 8 bits.
- Group the binary digits into groups of 4, starting from the rightmost digit.
- Convert each group of 4 binary digits to its equivalent BCD representation by converting the binary to decimal.
- Write down the BCD representation of each group, and concatenate the BCD digits together to get the final BCD representation of the decimal number.

**For example, let’s convert the decimal number 45 to BCD:**

- The binary representation of 45 is 00101101.
- Add leading zeros to make it 8 bits: 00000000 00101101.
- Group the binary digits into groups of 4: 0000 0000 0010 1101.
- Convert each group of 4 binary digits to its equivalent BCD representation:
- 0000 -> 0
- 0000 -> 0
- 0010 -> 2
- 1101 -> 13

- Write down the BCD representation of each group: 0000 0000 0010 1101, and concatenate the BCD digits together to get the final BCD representation of the decimal number: 0000000000101101.

Therefore, the BCD representation of the decimal number 45 is 0000000000101101.
