BigDicimal.round up
时间: 2023-08-24 07:04:41 浏览: 41
在BigDicimal中,round up是向上舍入的意思。也就是说,如果小数部分大于等于0.5,那么就将整数部分加1。举例来说,如果要将1.5舍入为整数,那么结果将是2。而如果要将1.2舍入为整数,那么结果将是1。这种舍入方式与四舍五入不同,它总是向上取整。<span class="em">1</span><span class="em">2</span><span class="em">3</span>

BigDicimal.ROUND_UP
BigDicimal.ROUND_UP表示将BigDecimal的小数部分进行向上舍入。当处理位大于等于5时,上一位数字加1,即远离0。这个舍入方式适用于正数和负数。当处理位小于5时,上一位数字不变,即靠近0。所以,当使用BigDicimal.ROUND_UP进行舍入时,处理数非0时,正数会远离0,负数会靠近0。<span class="em">1</span><span class="em">2</span><span class="em">3</span>

BigDecimal.ROUND_UP
BigDecimal.ROUND_UP is a rounding mode constant in the BigDecimal class in Java. It specifies that a BigDecimal value should be rounded up to the nearest value that is greater than or equal to the original value.
For example, if we have a BigDecimal value of 3.14159 and we round it up using the BigDecimal.ROUND_UP constant with a scale of 2 (meaning we want to round to 2 decimal places), the result would be 3.15.
This rounding mode is often used for financial calculations to ensure that decimal values are always rounded up to the next penny or cent, depending on the currency being used.
