The superior-billion is equal to 1,000,000,0001,000,000,000 = 109,000,000,000.[1] The term was coined by Garrett Wilkinson. It is equal to 1 followed by 9 billion zeros. It is 9,000,000,001 digits long. This number can be called fzbillion using the fz- prefix.[2].
Writing down the full decimal expansion would take 9,000 books of 400 pages each, with 2,500 digits on each page (except for the first, which would have 2,501).
