BigDecimal 怎么转换成int或者Long

for (DataRow objects : list) {
BigDecimal accepPass=null;
accepPass=(BigDecimal)objects.get("ACCEP_PASS");
}
我想把accepPass转换成int或者long.求高手指教

Answer 1

很简单，用intValue或者longValue方法即可。保证不超出int或long范围 你的代码修改成下面这种
for (DataRow objects : list) {
BigDecimal accepPass=null;
accepPass=(BigDecimal)objects.get("ACCEP_PASS");
int b=accepPass.intValue();
int c=accepPass.longValue();
System.out.println(b);//转int
System.out.println(c);//转long
} 有问题HI我或追问

Answer 2

BigDecimal big =new BigDecimal(2272626262626262.2341111114);
System.out.println(big.intValue()); System.out.println(big.longValue()); System.out.println(big.floatValue()); System.out.println(big.doubleValue()); 看看下面的结果吧

如下：

BigDecimal a=new BigDecimal(12.88);
int b=a.intValue();
System.out.println(b);//b=12;
