用Java表示货币价值 [英] Representing Monetary Values in Java

问题描述

据我所知，BigDecimal是在Java中表示货币价值的推荐最佳做法。你用什么？您是否更喜欢使用更好的库？

I understand that BigDecimal is recommended best practice for representing monetary values in Java. What do you use? Is there a better library that you prefer to use instead?

推荐答案

BigDecimal 一路走来。我听说有些人创建了他们自己的现金或 Money 类，这些类用货币封装现金值，但是在皮肤下它仍然是 BigDecimal ，可能与 BigDecimal.ROUND_HALF_EVEN 舍入。

BigDecimal all the way. I've heard of some folks creating their own Cash or Money classes which encapsulate a cash value with the currency, but under the skin it's still a BigDecimal, probably with BigDecimal.ROUND_HALF_EVEN rounding.

编辑：正如Don在他的回答中提到，有像 timeandmoney 这样的开源项目，虽然我赞扬他们试图阻止开发者不得不重新发明轮子，我对pre-alpha库没有足够的信心在生产环境中使用它。此外，如果你在引擎盖下挖掘，你会看到他们也使用 BigDecimal 。

As Don mentions in his answer, there are open sourced projects like timeandmoney, and whilst I applaud them for trying to prevent developers from having to reinvent the wheel, I just don't have enough confidence in a pre-alpha library to use it in a production environment. Besides, if you dig around under the hood, you'll see they use BigDecimal too.
