Обсуждение: Function to spell out a number

Hi everyone,
I've checked the manual and a bit online but could not find this:
Is there a provided function to spell out numbers in Postgres? (in
different languages if possible.)
For example:
to_words(1234) => 'two hundred and thirty four"
Kind regards:

There is a Perl module Number::Spell which has that functionality. It
supports all important languages, both British English and the American
English. You can write a plperlu function and grant execute on it to the
application user.

yes, cash_words(), it's deprecated.

not sure about that.

CREATE FUNCTION to_words(num integer) RETURNS text
AS $$
    DECLARE
       str TEXT;
    BEGIN
       str=cash_words(num * ('1.0'::money));
       str=REPLACE(str,' dollars and zero cents','');
       str=REPLACE(str,' dollar and zero cents','');
    RETURN lower(str);
    END;
$$
LANGUAGE plpgsql;

the type 'money' is deprecated, and the string 'dollar'
may be locale dependant so it's probably a bad idea to
do this.  This is probably why cash_words is not
mentioned in the 8.4 manual.

May be a better approach, but you'll still need find/write
rulesets, and figure out how to call it from postgres.



if this is for printing cheques just listing the digits
is acceptable in my exerience

to_words(1234) => 'one two three four'

this can done using repeated (or nested) replaces.
