BigDecimal详解、代码示例和经常遇到的坑
在给定的代码中,BigDecimal sum = new BigDecimal(0);创建了一个BigDecimal类型的变量sum,并将其初始值设置为0。但是,使用这种方式初始化BigDecimal可能会导致精度丢失问题。官方文档建议使用字符串形式来初始化BigDecimal,这样可以避免精度丢失。因此,在实际应用中,我们应该使用BigDecimal sum = new BigDecimal("0");来初始化sum变量。<span class="em">1</span><span class="em">2</span><span class="em">3</span><span class="em">4</span>
