Example:

    prefix="fmt" %>
    <p>Convert the number 14.3 with 4 decimal places</p>
    Formatting: <fmt:formatNumber value="123.4" type="NUMBER"  
    minFractionDigits="4" />

    Convert the number 14.3 to have 4 decimal places
    Formatting: 123.4000

In the above example we have used the 118N tag to add "4" decimal places to the number given.

Example:

    <%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt"%>
    <jsp:useBean id="dat" class="java.util.Date" />
    <fmt:formatDate value="${dat}" type="time" />

Result:

    1:44:40 PM

In the above we have used the "<:jsp:useBean/>" tag to include the java date class, using the format tag attribute "type" the time alone is displayed.
