The Most Perplexing Illusion Of All

Why don't we ever achieve one hundred percent?! Why is it that after 99 percent, we get an amount of nines after the decimal, and they keep iterating, just like the 1 is into three parts and a number three contains a decimal, and this decimal is composed of nothing, except for threes. Now tell me, what is i (imaginary number) to the ith power? Tell me, is that (ONE) not an imaginary number?!
