BigDecimal quotient = num1.divide(num2, 3, RoundingMode.HALF_UP); System.out.println("除法结果(保留三位小数):" + quotient); // 大于判断 // 使用 compareTo 方法进行比较。如果 num1 大于 num2,compareTo 返回值大于 0。 if (num1.compareTo(num2) > 0) { System.out.println(num1 + " ...
This method is used to return a BigDecimal object with a given scale and rounding mode. Here is a syntax. publicBigDecimalsetScale(intnewScale,RoundingModeroundingMode) newScaleis several digits to limit the precision or decimal places of a Bigdecimal.RoundingMode: Rounding Mode to apply to input...
BigDecimal divide ( BigDecimal divisor) This method returns a BigDecimal whose value is (this / divisor), and whose preferred scale is (this.scale() - divisor.scale()); if the exact quotient cannot be represented (because it has a non-terminating decimal expansion) an ArithmeticException is ...

BigDecimal方法会根据数字的具体精度位数,来判断是否需要使用科学计数法。 验证代码 publicstaticvoidmain(String[] args){BigDecimaldecimal=newBigDecimal("0.00000000000009");DecimalFormatdecimalFormatNumberOfDecimalPlaces2=(DecimalFormat) NumberFormat.getNumberInstance(Locale.CHINA); ...
除了使用强制类型转换,我们还可以使用BigDecimal类来进行精确的小数计算。BigDecimal类提供了高精度的十进制运算,可以避免浮点数运算时的精度问题。 importjava.math.BigDecimal;intdividend=7;intdivisor=3;BigDecimalbd1=newBigDecimal(dividend);BigDecimalbd2=newBigDecimal(divisor);BigDecimalresult=bd1.divide(bd2);System...
使用BigDecimal的divide方法进行除法运算。 BigDecimalresult=dividend.divide(divisor,MathContext.DECIMAL32); 1. 步骤3:设置保留位数 通过设置MathContext对象的precision属性来保留4位小数。 MathContextmc=newMathContext(4);result=result.round(mc); 1.
