16,700,000,000,000,000 = 1.67 x 10^16
start at the last 0....count the number of spaces till u can get a decimal right after the first digit....thats 16 spaces. Now take ur numbers that are not 0...1.67....and multiply it by 10^16...because of the 16 spaces. I hope I am making some kind of sense...I am better at doing then explaining how to do...lol
