title: Trying to convert decimal to decimal in DB2
body: <p>I have 25.555, I'm trying to convert to 25.555000.</p>
  <p>I used <code>CAST(25.555 AS DEC(9,6))</code>, but I'm getting the result as 25.554999.</p>
  <p>Note: Some are working fine( ex: 16.667 to 16.667000) but not all.</p>
  <ol>
  <li>The first integer is the total number of digits, it may range from 1 to 3.</li>
  <li>The second integer is the number of digits to the right of the decimal point, it may range from 0 to 6.</li>
