  ads:adSize="360x320"
  ads:adUnitId="@string/NativeAdId">
</com.google.android.gms.ads.NativeExpressAdView>

Answer 1

您可以使用to_char方法执行此操作：

select to_char(9.100000, '999.999') from dual 

select to_char(12679.1000001, '99999.999') from dual

使用表而不是使用常量值的示例：

with temp as (
    select 9.100000 as num from dual
    union
    select 12679.1000001 as num from dual
    union
    select -20.2356 as num from dual
)
select to_char(num,'99999.999')  from temp

放置SQL后放置3个DECIMAL
