Re: simple limit of decimals

dear Andreas,

thanks for the answer; yes, round should be the first, but it gives an
error: Function round(real, integer) does not exists

following this mail
(http://archives.postgresql.org/pgsql-bugs/2003-01/msg00074.php) I created a
new function and now works!

best regards,
Pere
