First thank you for this new field! I painfully missed that and now I am very happy to have this!
But how can I use this in a multilanguage environment?
You wrote: "In addition to this you've display formatting options to control how this field will display as a number on the users profile. You can optionally specify a thousands and decimal separator with both supporting language strings for localized formats. You'll find these new parameters under the Parameters > Display tab of your decimal fields as shown below."
What I have to do?
I added (for example for GERMAN) a language string (UE_THOUSANDS_SEP) in the field "Thousands Separator" and added him in the language override file ('UE_THOUSANDS_SEP' => '.'), but only the name of the language string is shown in the field, not the content.
