Ok, so in this video of mine, where I tried to define the floor function, the ceiling function and the rounding function, I seem to have made an error. For the ceiling function, the value of k is not supposed to be 5, but rather 4.999...9999, and while it may seem like the difference it doesn't matter, and it often doesn't, rounding functions such as the ceiling function, are an exception, and that small difference, is important. So basically, for the ceiling function, the value of k must be 0.4999...999, and not 5, and to define this value using summations would simply be 0.4 + a summation of 9*(10^-n), where n starts at 2, and goes on till infinity. I would once again like to apologize for my mistake, caused purely by negligence and lack of fact checking, and I promise that I shall try my best to avoid such errors in the future.

Have a good one boys!
