sqlite sum() of French decimal format numbers

When I realize this type of SQLite SQL query:

SELECT SUM(Column) as TOTAL_DEBIT FROM table_name;

I expect the addition of real but it gives me sum of integer division of numbers.

For exemple:

SELECT SUM(DEBIT) as TOTAL_DEBIT FROM DEBIT

The SQL query on the table below gives that:

TOTAL_DEBIT
11475

I wish I get this kind of result:

TOTAL_DEBIT
11482,79

Example Table :

   DROP TABLE IF EXISTS "DEBIT";
   CREATE TABLE "DEBIT" ("DATE" DATETIME NOT NULL , "DEBIT" REAL NOT NULL );
   INSERT INTO "DEBIT" VALUES('23/12/13','29,90');
   INSERT INTO "DEBIT" VALUES('23/12/13','304,00');
