Java：浮点格式取决于语言环境

问题描述

限时删除！！

我住在比利时。一般来说，在数学中，我们使用逗号来表示我们的小数：3,141592

这也是当我格式化浮点数时的结果。 b
$ b

  c> String.format（Locale.US，％f，floatValue）用于设置在格式化过程中使用的语言环境。
 
I live in Belgium. And generally, in mathematics, we write our decimals with a comma like this: 3,141592

And that is also the result when I format the float.
System.out.println(String.format("%f", 3.141592));
So, the . is replaced by a , like so: 3,141592. So always when I need a point instead I have to add something like this: String.format("%f", 3.14).replace(',','.');
So, the question is: is there a way to change the Locale which makes every formatter in  Java use a point, instead of comma?
Thanks
System.out.println(Locale.getDefault());
prints
nl_BE
 解决方案 
Try using String.format(Locale.US, "%f", floatValue) for just setting locale used during formatting.
