Force point (“.”) as decimal separator in java

Tags: , ,

I currently use the following code to print a double:

return String.format("%.2f", someDouble);

This works well, except that Java uses my Locale’s decimal separator (a comma) while I would like to use a point. Is there an easy way to do this?


Use the overload of String.format which lets you specify the locale:

return String.format(Locale.ROOT, "%.2f", someDouble);

If you’re only formatting a number – as you are here – then using NumberFormat would probably be more appropriate. But if you need the rest of the formatting capabilities of String.format, this should work fine.
