Convert a number to have 2 decimal places in Oracle
I have a number column whose values I will like to convert into a number with 2 decimal places.
For example the number 1234 should become 1234.00
I tried the formula
SELECT TO_NUMBER(TO_CHAR(1234, '9999.00')) FROM DUAL
Output is 1234
I would have prefer it to be 1234.00
The output should be in number format.
Any ideas

SELECT TO_CHAR(1234, 'fm99D00')
FROM DUAL;

You're confusing a number with the string representation of a number.

A number is just the digits that make up the number. There is no difference between 1234 and 1234.00 - they're both the same floating-point number.

Databases shouldn't be concerned with formatting values for display. Instead, you should be storing the number in the database, and formatting it appropriately in the front-end application that displays the value to the user.
