.99999..... does not equal 1. It can be rounded up to 1, or if you add .000000000000000000000000000000000000000000001 then yes, it will be one, but in the end, without adding or rounding, it is not one.
This is like saying that does 30 = 50? No, it does not.
20.9=21? No it does not
35=11234? No, it does not.
All numbers have a specific place on the number line. They will stay on that spot, until you add or subtract from that number. Otherwise, they cannot magically shift, unless God wants it to move.

Bing bang boom, solved this question
