比较BigDecimal是否大于零 [英] Compare if BigDecimal is greater than zero

问题描述

如果BigDecimal值大于零，如何比较?

How can I compare if BigDecimal value is greater than zero?

推荐答案

它很简单:

if (value.compareTo(BigDecimal.ZERO) > 0)

compareTo 的文档实际上指定它将返回-1、0或1，但是更通用的Comparable<T>.compareTo方法仅保证在适当的三种情况下小于零，零或大于零-所以我通常只是坚持比较.

The documentation for compareTo actually specifies that it will return -1, 0 or 1, but the more general Comparable<T>.compareTo method only guarantees less than zero, zero, or greater than zero for the appropriate three cases - so I typically just stick to that comparison.
