Roger,
You can always write your own Round() function and have it
round exactly the way you want.
To round up on a decimal digit 5 use:
mysql> select truncate(1.235+0.005,2) rounded;
+-+
| rounded |
+-+
|1.24 |
+-+
1 row in set (0.00 sec)
To round down
Hi all,
ROUND decimal value is the mis-understood between MySQL internal
function and another environment/programming. I found that MySQL-Round is
correct within the suitable of itself (you can say it correct in C library
or other word it correct in technical term), but it did not use

As far as I can tell, there is no "MySQL round"... as
This round discussion has nothing to do with floating point
approximations.
Most round routines are statistically biased on the high side. The MySQL
round is statistically correct. The more accurate rounding rule is
If digit following the column you are rounding is a 5

Well, IMHO no, a bug is an unexpected flaw.

Hi,
there are a couple of bugs related to the round() function. (See the thread
'Can somebody help me with "round (columna,columnb) "?')
One bug is already well known and documentet, it is related to different C
library implementations on different platforms: the result of round(2.55,1)
