BigDecimal的用法
BigDecimal.ROUND_HALF_UP是Java中BigDecimal类的一个常量,用于指定舍入模式。具体来说,它表示使用四舍五入的方式来进行舍入操作。在这种舍入模式下,如果小数点后一位大于等于5,则向上舍入;如果小数点后一位小于5,则向下舍入。在给定的代码示例中,通过调用setScale方法,并传入2和BigDecimal.ROUND_HALF_UP作为参数,将BigDecimal对象的小数部分保留两位并进行四舍五入操作。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
