title: Round without round function python
body: <p>I'm new to Python and a friend challenged me with a simple question that I'm stumped on:  please build me a simple program that rounds numbers without using any mathematical operations, like ROUND. I just want to figure this out for a single decimal place - like 2.1 or 5.8 - nothing fancy with long decimal places.  I beleive that it's something like an if/then statement - if &lt; 5 then do.....do what?  Thank you in advance!!</p>
