BigDecimal判端为0

BigDecimal可以通过compareTo方法来判断是否为0。compareTo方法返回一个整数，表示调用对象与指定BigDecimal对象的比较结果。如果返回值为0，则表示两个BigDecimal对象相等。因此，可以通过调用compareTo方法，将0作为参数传入，来判断BigDecimal是否为0。例如，假设我们有一个BigDecimal对象bd，我们可以使用以下代码来判断bd是否为0：

int result = bd.compareTo(BigDecimal.ZERO);
if(result == 0) {
// bd等于0
} else {
// bd不等于0
} <span class="em">1</span><span class="em">2</span><span class="em">3</span>
