Hi Paul,

It's kinda 'old school'.

It's an attempt to avoid 'systematic bias'.  If you _always_ round your
numbers up (or down) you end up overstating (or understating) your
estimate of the population mean, for example.

{Of course, you'd need a pretty darn precise result set for this
difference to be 'statistically significant'.
But it is theoretically possible.}

I'm not sure when people stopped using the 'x.5 to nearest even integer'
rounding convention. I think somewhere along the line the education
system must have decided it was "too hard" and stopped teaching it.

I'm fairly sure that round(), in VBScript, rounds to the nearest
even integer (e.g. answer mod 2 = 0) when the answer ends exactly in .5.

1.5 -> 2
2.5 -> 2

I don't know why that is.
