(In reply to Zeros and Ones by John)

John, If you intend the binary representation of 450, it's 111000010. You show the digits in reverse order, explaining why you put a leading zero in. Convention dictates high order to low order. Why not 11100001, representing the decimal 225 itself? But see my previous comments about bases, as well as Ravi's.
