推荐答案

看了谷歌之后，似乎你的计算转换为usd有点偏。

1欧元= 1.3081美元
1日元= 0.00826036676美元
1英镑= 1.9539美元

我离开了用你的计算代码。如果您需要帮助或者甚至想要这些计算，请告诉我，我会帮助您将它们放入

after looking at google it seems as if your calculations to convert to usd is a bit off.

1 Euro = 1.3081 U.S. dollar
1 Japanese yen = 0.00826036676 U.S. dollar
1 British pound = 1.9539 U.S. dollar

I left the code with your calculations in it. if you need help or even want these calculations in it let me know and i will help u put them in

您可以使用对象。


创建实例时，请设置唯一属性 - 金额，货币格式和日期。用对象原型中的汇率数组设置转换方法（往返）。


这使得添加新货币或更新汇率变得微不足道（这就是你需要为每笔交易附上日期的原因。）

You could use an object.

When you create an instance, set the unique properties- amount, currency format, and date. Set the conversion methods (to and from) with arrays of exchange ratesin the object''s prototype.

This makes it trivial to add new currencies, or update the exchange rates- (which is why you need a date attached to every transaction).
