I like the look of \\(\lceil \frac{n}{2} \rceil\\) a lot more than \\( \lfloor \frac{n+1}{2} \\rfloor \\), because it goes along better with my story about the "best approximation from above" to \\(\frac{n}{2}\\). That's why I was so confused by Alex Varga's answer. But they're equal! You learn something new every day.

I don't know a name for this phenomenon, Cole.
