title: Convert integer or decimal number to string
body: <p>I need to convert numbers in text format. It could be integers and decimal numbers. </p>
  
  <p>If convert integer without <code>regexp_replace</code> like </p>
  
  <p><code>select to_char(999,'FM9999.9') from dual;</code></p>
  
  <p><code>999.</code></p>
  
  <p>Solution for this problem is 
  <code>regexp_replace(to_char(999.9,'FM9999.9'),'[.]$')</code></p>
  
  <p>Are there any other way to do it without <code>regexp_replace</code> ?</p>
