Prevent oracle suppresses the leading zero

Question

Hi guys,
What is the best way to prevent oracle from suppressing leading 0 while convert a number to char. I am using Release 11.2.0.1.0.
Connected to:
Oracle Database 11g Enterprise Edition Release 11.1.0.7.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options
SQL> select to_char(0.01) from dual;
TO_
.01I can achieve this by using decode, for example:
SQL> select decode(instr(to_char(0.01), '.'),
  2                1,
  3                '0' || to_char(0.01),
  4                to_char(0.01)) val
  5    from dual;
VAL
0.01
SQL>But it doesn't look very pretty, is there a better way to do this please? Please note my data is mixed with values with or without decimal places. When the value is greater equal than 1, i want to have the output as same as to_char(val), the padding zero only applies to when the value is between 0 to 1. Many thanks.
Best regards,
Pete

Many thanks Justin, but it doesn;t give quite what i want
SQL> select to_char(1, '0.99') col from dual;
COL
1.00
SQL>Please note my data is mixed with or without decimal places, for example value 123, i just want to show 123, NOT 123.00 instead. At the moment i am using decode to do this as:
SQL> select decode(instr(to_char(123), '.'),
  2                1,
  3                '0' || to_char(123),
  4                to_char(123)) val
  5    from dual;
VAL
123
SQL>It works but it looks ugly to me, I wonder is there a better way to do this please?
Cheers,
Pete
