title: Convert float value from a db2 database to a date format?
body: <p>I have a database from a custom application.
  The values in the database for a date is <code>44416.254005</code>, and the application that uses this database resolves that number to the following date <code>8/8/2021 6:05:46 AM</code>.
  Another example is <code>44416.268113</code> to <code>8/8/2021 6:26:05 AM</code>.
  ex. 44328.93713 = 5/12/2021 10:29:28 PM</p>
  <p>I have an old backup of this database and need to figure out how the conversions are made?</p>
