Question

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

Answer 1

Try using String.format(Locale.US, "%f", floatValue) for just setting locale used during formatting.
