title: String conversion from numeric to string in awk
body: <p>I have below <code>awk</code> command which give mentioned result as well.</p>
  
  <pre><code>echo '1600000.00000000' '1600000.0000' | awk '{ print ($1 != $2) ? "true" : "false" }'
  </code></pre>
  
  <p>Result is : - <strong>false</strong></p>
  
  <p>As per numeric value the result given by the command is correct.
  But I want command must consider both input(<code>'1600000.00000000'</code> <code>'1600000.0000'</code>) as <code>string</code> and give the result as <code>true</code>. Because If you consider both input as <code>string</code> then they are not equal difference is there in precision.</p>
