log10(16777216) = about 7.22 decimal digits.

log10(8388608) = about 6.92 decimal digits.

However, the top bit is normally counted in those circumstances : it's the 
only bit to be significant even though it can't be a zero and it doesn't 
have to be recorded. It's just like the first decimal digit has to be 
between 1 and 10 because it can't be a zero.

So the answer is 7.22 decimal digits.

(Yes, Pd could have used 7 decimal digits but uses 6 instead)
