0.0001 is a number that is almost 0.0002, but not quite 0.0000.
0.0001 is the nerd of the number community - it's really smart but very insecure and no one really wants to hang out with it. As a result, scientists have devised various alternatives to 0.0001. The easiest is to divide by 0 and then un-divide by zero to end up with the same number j00 started with. You could also use 0.1 as a starter then divide by a million, un-divide by a thousand then re-divide by 100,000 and un-re-divide by 400 billion - which will leave you with 0.0001.
