BigDecimal详解、代码示例和经常遇到的坑
BigDecimal中的divide方法是用来进行除法运算的。该方法的声明是public BigDecimal divide(BigDecimal divisor,int scale, int roundingMode)。其中,divisor是除数,scale是计算所得商的小数点后的位数,roundingMode是近似处理模式。通过调用该方法,可以得到除法的结果。例如,在以下示例代码中,我们创建了两个BigDecimal对象b1和b2,然后使用divide方法进行除法运算,并指定了小数点后的位数和近似处理模式:
```
BigDecimal b1 = new BigDecimal(10.005);
BigDecimal b2 = new BigDecimal(2);
BigDecimal result = b1.divide(b2, 3, BigDecimal.ROUND_UNNECESSARY);
System.out.println(result);
```
在这个例子中,我们将b1除以b2,将结果保留3位小数,并且指定了不需要进行近似处理的模式。运行这段代码,将会输出除法的结果。<em>1</em><em>2</em><em>3</em>
