jstl c:if怎么判断两个值大小

	                    	 <c:forEach items="${netNameAuditmap}" var="item" varStatus="c">
	                    	  <tr class="chart_table_even">
	                        	<td>
	                            	<span class="xuhao_con">${c.count}</span>
	                            </td>
	                            <td>
	                            	<span class="diqu_con">${item.area} </span>
	                            </td>
	                            <td>
	                            	<span class="zongliang_con">${item.amount}</span>
	                            </td>
	                            <td>
	                            	<span class="baifenbi_con">
	                                	<div class="baifenbi_num">${item.cal}</div>
	                                	<div class="baifenbi_tiao">
	                                    	<div class="baifenbi_tiao_in"></div>
	                                    </div>
	                                </span>
	                            </td>
                                <td><span class="zongliang_con">${item.day0}</span></td>
                                <td><span class="zongliang_con">${item.day1}</span></td>
                                <td><span class="zongliang_con">${item.day2}</span></td>
	                            <td>
	                            	<span class="qushi_up"></span>
	                            </td>
	                         </tr>
                          </c:forEach>

红页部分我想判断${item.day1}和${item.day2}大小 如果${item.day1}显示<span class="qushi_up">，如果小不显示，该怎么写
------解决方案--------------------
<c:if test=${item.day1>item.day2}>这里写你要显示的数据</c:if>
