In Estonia is float numbers format allways with leading zero ( 0,1 ). My NLS settings are:
NLS_TERRITORY = ESTONIA
NLS_LANGUAGE = ESTONIAN

but float numbers are converted to text without leading zero.

select to_char(0.1) from dual;
result: ,1

This is absurd when I need to insert number format everywhere, when I'm using my territory NLS.

so, how can I set the default number conversion format?

You need to issue a format mask.
Check here for the correct format.

Do you mean that I need allways put format into to_char?

to_char(0.1, '99,999')

This is absurd. I want write SQL's like this:

select 'Price is ' || UNIT_PRICE || ' EURO '
from PRICES

This is not absurd.
SQL is a language to extract data from a database, so your query fetches what's in the db. In the database, your value is stored as a number.
Now it's up to your front-end application to display the data fetched through SQL in the way you desire.

So there is no possibility to set default number format. I must declare constant in PL/SQL and put it every to_char() function manually.

Depends on your front-end tool.
