java - 具有货币格式的 JSF convertNumber 是否舍入或截断额外的小数位？

Question

这是一个例子:

    <h:outputText value="#{myBean.myMoney}">
       <f:convertNumber type="currency" currencySymbol="$" />
    </h:outputText>

鉴于我有 1.006 美元，这会输出 1.00 美元还是 1.01 美元？

这里不说: http://java.sun.com/javaee/javaserverfaces/1.1_01/docs/tlddocs/f/convertNumber.html

Answer 1

Answer=四舍五入

嗯……听起来对吗？我不认为凑钱是个好主意。希望没有银行应用程序会依赖这个。

让人想起《飞越布谷鸟巢》中的这一幕……

[the inmates are playing cards and betting with cigarettes]
Martini: [rips a cigarette in half] I bet a nickel.
McMurphy: Dime's the limit, Martini.
Martini: I bet a dime.
[Puts the two halves onto the table]
McMurphy: This is not a dime, Martini. This is a dime.
[shows a whole cigarette]
McMurphy: If you break it in half, you don't get two nickels, you get shit. Try and smoke it. You understand?
Martini: Yes.
McMurphy: You don't understand.
