在这一步,我们将double类型的乘法结果result转换为BigDecimal类型,以便进行精确计算。 步骤四:比较两种计算结果 // 比较两种计算结果if(result!=preciseResult.doubleValue()){System.out.println("乘法运算结果存在精度丢失!");}else{System.out.println("乘法运算结果精确!");} 1. 2. 3. 4. 5. 6. 在这一...
public BigDecimal(double val)Translates a double into a BigDecimal which is the exact decimal representation of the double's binary floating-point value. The scale of the returned BigDecimal is the smallest value such that (10scale × val) is an integer.Notes: Parameters: val - dou...
