I'm trying to create a ratings system that shows 1/2 values. Quick
question, what would be the easiest way to round a value to the nearest .5
of a number? I'm trying to avoid multiple if/elses.
i.e. 3.21 would round to 3
i.e. 3.31 would round to 3.5
i.e. 3.61 would round to 3.5
i.e. 3.91 would

No it doesn't! I suspect your typing thumbs, or is it your ring finger,
is making you look like a bad mathematician! ;-)

Sweet! Many years ago, in high school Algebra class, I would have been able
to figure that out. It's amazing what we forget.

Oops, you're right, Ian. That should be 7 / 2 == 3.5 (remove the
second three), of course. I wonder who had coffee this morning and
therefore can't control his fine motor skills. At least with a
computer your assertions are actually checked, so typos get caught.
