There you go avoiding the question yet again. By construction N has to be an integer. You can't say f(x)=x+x+... (3.5 times) because that doesn't make sense. You can have f(x)=x+x+x, which is 3 times, or you have have f(x)=x+x+x+x, which is 4 times. Would you, in your next post, EITHER answer the question OR concede that I am right.
