Subj:   Re: Rounding in Teradata
 
From:   Todd A. Walter

And... the IEEE standard comes from statistics. The engineers and statisticians building the early Intel CPUs only supported the "statistically correct" method. I do noot remember exactly but it was not until the 486 or first Pentium that Intel supported the "business" definition of rounding. Since Teradata had always supported rounding as delivered by the CPU, when we made the "round halfway" flag, we left the default as it had been to avoid surprise to existing applications.

The round flag is the right way to solve this issue if your organization requires the business definition rather than the statistical one.
