From the "Oracle 9i SQL Reference"

Chapter 2: "Basic Elements of Oracle SQL", "Format Models", Table 2-13 "Number Format Elements": X

Returns the hexadecimal value of the specified number of digits. If the specified number is not an integer, then Oracle rounds it to an integer.


* This element accepts only positive values or 0. Negative values return an error.
* You can precede this element only with 0 (which returns leading zeroes) or FM. Any other elements return an error. If you specify neither 0 nor FM with X, then the return always has 1 leading blank.
So, you can use it as follows:
select to_char(1515,'XXXX') x
from   dual

[edit]Drat! Forgot that site Frank mentioned!
