It seem
Round function was discuss on this group. They tell me that it
used round with the C behavior to adjust value near even value. If you
need to adjust with upper value after .5, you need to used programming
language (PHP, VB, C) instead of MySQL round function.

No, this was a misunderstanding... this is what I did:

Oops, I seem to have stirred up a hornet's nest! (must be a talent of mine).

As far as I can tell, there are at least two bugs.
One bug is already known, it is the rounding error that applies to some
platforms, depending on the underlaying C li

Hi Dan,
Your suggestion works but it slows down things a lot.
Thats just a workaround, my quick tests showed it takes about 30% longer for
the query to complete...
It seems to be a bug in mysql, but the problem is that my whole thing is
running fine on a bigger production system and I'd not lik

Hi.
IMHO your query should work. This looks like a bug to me. I can
confirm this on 3.23.46, but have no more current version available
for testing.
