>>11548353>>11548353alright I will finish my thought
if this number starts with 1 or something greater than 1 then it will automatically will be greater than 1 because after the comma will follow some other digits and unless they are all 0 it will be strictly greater than 1 (and they cannot be all equal to 0 because then that number c would be equal to 1)
for the same reason it cannot start with -1 or lesser than -1 - it would be lesser than 0,99999...
so it starts with 0,...
next digit should be any from {0,1,2,3,4,5,6,7,8,9} if it is any of the {0,1,2,3,4,5,6,7,8} this number will be automatically lesser than 0,9999999 so the second digit should necessarily be 9.
But the same goes for the third digit or the fourth etc
So this number c is equal to 0,9999999.....
A contradiction.
Therefore, 0,99999.... = 1.
