title: SQL Server compare numbers after decimal point
body: <p>We have some numbers values in SQL server database such like <code>7.11 and 7.6</code>. 
  Actually <code>7.11 is later version than 7.6</code>, when using "<code>max(vernum)</code>" in SQL server, it will return <code>7.6</code>. How can we let SQL server return <code>7.11</code>?
  Thanks </p>
