两个int相除并保留2位小数

要计算两个int相除并保留2位小数，可以使用BigDecimal类来实现。首先将两个int转换为double类型，然后使用BigDecimal的divide方法进行除法运算，并设置保留小数位数为2。最后使用setScale方法将结果保留2位小数并转换为double类型。

代码示例：

int num1 = 6;
int num2 = 9;
BigDecimal result = BigDecimal.valueOf((double) num1 / num2).setScale(2, RoundingMode.HALF_UP);
double resultDouble = result.doubleValue();

其中，num1和num2分别代表两个int，result是BigDecimal类型的结果，resultDouble是最终保留2位小数的double类型结果。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
