I concur with Eric that this should be closed.

They're not "incorrect results", they are correct results, or at least *better* results. We did not invent the so-called Banker's Rounding technique, it has been the standard used by the American Society for Testing and Materials (ASTM) since 1940, and was in common use even before that.

(Despite the name, there's very little evidence that it has been used by bankers.)

I am sorry that you expected different results and a worse rounding technique. The method of rounding taught in high schools is worse because it leads to bias. I'm sorry that you have been taught a poor rounding technique, but not everyone expects the same results you do.

See previous issue #41598 and likely others.
