我如何指定保存两个其他字段之和的字段应该能够显示高于$ 999.999.99的值作为美元和美分？
表格的源代码如下。
当我测试表单时，我在amount_1中输入999999.99并显示$ 999,999.99。我在amount_2输入.01。 total_amount字段显示$ 1.0E。我希望它显示$ 1,000,000.00并且给出错误或不正确的值错误。
我尝试过使用文本输出控件，但遇到了同样的问题。
我正在编写一个使用Form Runner从银行代理请求数据的银行应用程序，因此浮点字段不够准确。
我看了几篇与输出效果相关的帖子，但没有看到任何帮助。我正在使用各种数据类型的默认输出格式。
感谢您的帮助。

使用xforms:output并使用格式化这样的值。
<xforms:output bind="total_amount-bind" xxforms:format="format-number(., $ ###,###.##)" />
