[Mono-list] Maths

[Tom Cabanski]

In the science disciplines, n.5 is rounded to the nearest even integer
(e.g. 1.5 rounds to 2, 2.5 rounds to 3 and 3.5 rounds to 4).  If you
think about it, that is actually more accurate that always rounding as
.5 is exactly in the middle and we should round up about half the time
and down the other half of the time.

This is one of the first platforms that behaves the way I would expect
in this area.

I get the same results with csc from MS .NET 1.0.
