fmt:formatNumber use locale display negative currency in -$xxx.xx format in JSTL
First, we want to know our own locale,how to display the locale in a JSTL?
<c:out value="${pageContext.request.locale.language}"/>
I'm confused with the jstl tag libs:
I want to format a number to a currency with german style
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt" %>
<html>
<head>
<title>format number</title>
</head>
<body>
<c:set var="val" value="40.52" />
<p> Currency in USA
<fmt:setLocale value="en_US"
scope="session"
/>
<fmt:formatNumber value="${val}" type="currency" />
</p>
<p>Currency in Germany
<fmt:setLocale value="de_DE"
scope="session"
/>
<fmt:formatNumber value="${val}" type="currency"/>
</p>
</body>
</html>
And thats the output:
Currency in USA $40.52
Currency in Germany 40,52 €
I am using fmt:formatNumber to format currency in JSTL, it will display negative currency in ($100) format, if you want to make it display negative currency in negative format instead of ($100). I would suggest:
<c:set
var="val" value="46563746375"/>
<fmt:formatNumber
value="${val}"
pattern="###.###E0"/>
