round(); eg
select round(foo, 2)
from bar
...will give you values in column foo rounded to 2 decimal places.

If you use "numeric(x,2)", where x is the largest
number of digits you are likely to need, the rounding
will be done for you. Type "money" is deprecated
anyway, and is likely to be dropped in a future
release. You can format the numeric value on output
if you want to display currency symbols or whatever.
