15. Use the double-dabble method to convert 102123 directly to decimal. (Hint: you have to change the multiplier.)
To convert the number 102123 to decimal using the double-dabble method, follow these steps:
Start with the binary representation of the number, which is 0001 0000 0010 0001 0010 0011 in binary.
Initialize a multiplier with the value of 5 (in decimal). This is because we are dealing with 6 digits, so we will be multiplying by 5, 4, 3, 2, 1, and 0 in successive iterations.
Perform the double-dabble algorithm:
After performing the double-dabble algorithm, the binary representation becomes: 0000 0001 0000 0000 0000 0100 in binary.
Convert the binary representation to decimal:
Therefore, the decimal representation of 102123 is 10004 using the double-dabble method.
