根据语言/整理设置,似乎无法使用正确的分隔符将float转换为varchar？

这是一个错误吗？

set language german --makes no difference in this case
declare @f float = 4.5
select @f --output in my management studio is 4,5 
          --according to the regional os settings this is correct

select convert(varchar,@f) -- output: 4.5 not correct

一个解决方案,但我认为并不理想

select replace(convert(varchar,@f),'.',',')
