Assuming 'n' is your number, use #round(n * 2) / 2#
For example:
3.21 * 2 == 6.42
round(6.42) == 6
6 / 2 == 3
3.31 * 2 = 6.62
round(6.62) == 7
7 / 2 == 3.35

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.

That is beautiful in form and simplicity. Bravo.
