A given BCD number can be converted into an equivalent binary number by first writing its decimal equivalent and then converting it into its binary equivalent. The first step is straightforward, and the second step was explained in the previous chapter. As an example, we will find the binary equivalent of the BCD number 0010 1001.0111 0101:
• BCD number: 0010 1001.0111 0101.
• Corresponding decimal number: 29.75.
• The binary equivalent of 29.75 can be determined to be 11101 for the integer part and .11 for the fractional part.
• Therefore, (0010 1001.0111 0101)BCD = (11101.11)2.
