1548877 - Number​..toLocale​String(locale) does not work correctly with certain locales

Status: RESOLVED DUPLICATE of bug 1522070

(Core :: JavaScript: Internationalization API, defect)

Description

[emil]

User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Ubuntu Chromium/71.0.3578.80 Chrome/71.0.3578.80 Safari/537.36

Steps to reproduce:

Consider the following JS expression: (123.456).toLocaleString("no"). It returns a string without comma as the decimal separator. Norwegian uses the comma as the decimal separator.

(123.456).toLocaleString("nb") and (123.456).toLocaleString("nn") both work however, which is correct. Both nb and nn has the macrolanguage no according to the language subtag registry https://www.iana.org/assignments/language-subtag-registry/language-subtag-registry.

Expected results:

123,456

Hi, Im not entirely sure this is the correct component, but it seems like a good place to start, Please change the component to a more suitable one if this is not the correct one.

That's not what I see in Firefox console. On which version are you trying?

(123.456).toLocaleString("no")
"123,456"
(123.456).toLocaleString("nb")
"123,456"
(123.456).toLocaleString("nn")
"123,456"

I also assume you meant thousand separator in comment 1 (not decimal)?

Side note: this data is not Mozilla's, it comes from CLDR (Unicode). If there are issues, they likely need to be reported upstream

The language identifier no is currently not supported.

js> Intl.NumberFormat.supportedLocalesOf(["nb", "nn", "no"])
["nb", "nn"]

But bug 1522070 should fix this issue by mapping no to nb per CLDR.
