Golang get decimal separator for current culture

Is there a way in Golang to get the current OS decimal separator in windows?

I know that in the Geographic area settings in control panel you can assign your custom decimal separator, so there must be a way to get this value... or no?

I want to use fmt.Printf() and format any float with the OS current decimal symbol.

To get the current language OS, you might use a cross platform package such as https://github.com/cloudfoundry-attic/jibber_jabber

To print localized texts you might use the text package available here https://godoc.org/golang.org/x/text

Example

package main

import (
"fmt"

"github.com/cloudfoundry/jibber_jabber"
"golang.org/x/text/language"
"golang.org/x/text/message"
)

func main()
userLanguage, err := jibber_jabber.DetectLanguage()
if err != nil
panic(err)

fmt.Println("Language:", userLanguage)

tagLanguage := language.Make(userLanguage)
fmt.Println("Language:", tagLanguage)


p := message.NewPrinter(language.BritishEnglish)
p.Printf("There are %v flowers in our garden.n", 1500)


p := message.NewPrinter(tagLanguage)
p.Printf("There are %v flowers in our garden.n", 1500)




As you can see you don t directly use the fmt package anymore, instead you have to create a Printer and use this one to display the texts appropriately.

fmt

Printer

I have not been able to determine how to extract this information from the text package.
