title: Oracle: Pattern for to_char(number) to add additional ascii characters?
body: <p>Using the Oracle to_char(number) function, is it possible to append ascii characters to the returned string?</p>
  
  <p>Specifically, I need to add a percentage character to the returned string.</p>
  
  <p>"select to_char(89.2244, '999G999G999G999G990D00') from dual" -->
  returns "89.22". I need a format pattern that returns "89.22%".</p>
  
  <p>I am using this through reports in Application Express, so cannot simply concatenate "%" to the query, i need to put it in the number format.</p>
