How to keep the zero after decimal

Question

Hi,
I'm trying to store numbers into one of the custom table column. This column must contain unique value for each record.
Now the issue is if i want to insert a record with zero after decimal point its removing that zero.
Emp Id (number)
1234.1
1234.2
1234.9
1234.10 --> 1234.1 (this is what is getting stored in table)
1234.11
...I want to store 1234.10 not 1234.1, is there any way that i can store zeros as well after decimal point for NUMBER data type column.
Thanks in advance,

Hi,
Your appending sequence number should be with leading zeroes like
1.001
1.002
1.003
1.009
1.01
1.011 etc
based on the numbe rof records you haveTry this and see if this fits for you
DECLARE
   CURSOR c1 IS SELECT * FROM custom_table1;
   i              NUMBER;
   l_len          NUMBER;
BEGIN
   SELECT LENGTH (COUNT (*))+(LENGTH(some_seq.currval)-1) INTO l_len FROM custom_table1;
   FOR c1_rec IN c1
   LOOP
      i           := some_seq.NEXTVAL;
      INSERT INTO test_tab (ID, NAME, amount, create_date)
           VALUES (c1_rec.ID || '.' || TO_CHAR (i, rpad ('0', l_len, '0') || '9')
                  ,c1_rec.NAME
                  ,c1_rec.amount
                  ,c1_rec.create_date);
   END LOOP;
END;G.
