Rod, you don't understand me. :)
I needn't round, or the valueless zeroes too.
It's good (in older version of pSQL):
2.000::numeric -> 2
2.001::numeric -> 2.001
It's "ugly" (in 7.3):
2.000::numeric -> 2.000
2.001::numeric -> 2.001
or
round(2.000::numeric,2) -> 2.00
round(2.001::numeric,2) -> 2.00
Joel had got a good idea:
joel@joel=# select rtrim(rtrim('2.000'::numeric, '0'),'.');
rtrim
-------
2
(1 row)
.. but i prefer the old text(numeric) function :)
Thanks!
