Rick,

FYI, the round-to-even method is what I was taught all the way back into the '60's when I was in late elementary/early junior high school. It was drilled into me that this was the appropriate method to avoid bias if your data have half-unit values. I was really amazed that the SAS ROUND function rounded all half-units down. I developed my own work-arounds, but that was always inconvenient.

It was at my persistent urging to SAS that the RoundE function was introduced. I argued that RoundE was the IEEE standard and that it could be important for bias reduction, a major issue for a language that was named the Statistical Analysis System. If you can't estimate the most basic statistic without bias, then that is a problem. Those arguments prevailed and I was even given naming rights to the function. That is quite a few years ago, now.
