在Java中截断BigDecimal值
在Java中截断BigDecimal值,请尝试以下代码。
在这里,我们采用了两个BigDecimla值,并设置了舍入模式以舍去十进制值-
示例
import java.math.BigDecimal; public class Demo { public static void main(String[] argv) throws Exception { int decPlaces1 = 3; int decPlaces2 = 5; BigDecimal val1 = new BigDecimal("37578975587.876876989"); BigDecimal val2 = new BigDecimal("62567875598.976876569"); System.out.println("Value 1 : "+val1); System.out.println("Value 2 : "+val2); //ROUND_DOWN- val1 = val1.setScale(decPlaces1, BigDecimal.ROUND_DOWN); String str1 = val1.toString(); System.out.println("Result = "+str1); //ROUND_UP- val2 = val2.setScale(decPlaces2, BigDecimal.ROUND_UP); String str2 = val2.toString(); System.out.println("Result = "+str2); } }
输出结果
Value 1 : 37578975587.876876989 Value 2 : 62567875598.976876569 Result = 37578975587.876 Result = 62567875598.97688
