---El expression retains two decimal places, retains two decimal places using JSTL <fmt:formatNumber> tags

<%@ taglib uri= "http://java.sun.com/jsp/jstl/fmt" prefix= "FMT"%>
<fmt:formatnumber type= "number" value= "${688.87 * 0.8}" pattern= "0.00" maxfractiondigits= "2"/>

< TD ><  type= "number"  value= "${item.lakecoin}"  pattern= "0.00"  /></td>

<fmt:formatnumber type= "number" value= "${LB.MONBZFJ}" maxfractiondigits= "2"/> What does maxfractiondigits= "2" mean here?

Max fraction decimal digits number of digits
Maximum number of decimal digits = 2

---JSP page shows red when a variable is negative

<TDNoWrap class= "TDJJ"Align= "Center">    <c:ifTest= "${list.profitmoney < ' 0 '}">        <FontColor= "Red">${list.profitmoney}</Font>    </c:if>    <c:ifTest= "${list.profitmoney >= ' 0 '}">        <FontColor= "BLACK">${list.profitmoney}</Font>    </c:if></TD>

${list.profitmoney} is the value of a variable that is queried by a JSP page.

The above code is to implement if negative, the font color is marked red. If positive or 0, the font color is black.

<TDMethods of >//if  <c:ifTest= "${item.anxcoin<0}">        <FontColor= "Red"><Fmt:formatnumbertype= "Number"value= "${item.anxcoin}"pattern= "0.00" /></Font>  </c:if>  <c:ifTest= "${item.anxcoin>=0}">        <Fmt:formatnumbertype= "Number"value= "${item.anxcoin}"pattern= "0.00" />  </c:if></TD>

Method of Choose when otherwise

<TD><C:choose>    <C:whenTest= "${item.anxcoin<0}">        <FontColor= "Red"><Fmt:formatnumbertype= "Number"value= "${item.anxcoin}"pattern= "0.00" /></Font>    </C:when>    <c:otherwise><Fmt:formatnumbertype= "Number"value= "${item.anxcoin}"pattern= "0.00" /></c:otherwise></C:choose></TD>
