- - ### Field Detail

    - #### STANDARD

          public static final DecimalStyle STANDARD

      The standard set of non-localized decimal style symbols.

      This uses standard ASCII characters for zero, positive, negative and a dot for the decimal point.

  - ### Method Detail

    - #### getAvailableLocales

          public static Set<Locale> getAvailableLocales​()

      Lists all the locales that are supported.

      The locale 'en_US' will always be present.

      Returns:
        a Set of Locales for which localization is supported

    - #### ofDefaultLocale

          public static DecimalStyle ofDefaultLocale​()

      Obtains the DecimalStyle for the default `FORMAT` locale.

      This method provides access to locale sensitive decimal style symbols.

      This is equivalent to calling `of(Locale.getDefault(Locale.Category.FORMAT))`.

      Returns:
        the decimal style, not null
      See Also:
        `Locale.Category.FORMAT`

    - #### of

          public static DecimalStyle of​(Locale locale)

      Obtains the DecimalStyle for the specified locale.

      This method provides access to locale sensitive decimal style symbols.

      Parameters:
        `locale` - the locale, not null
      Returns:
        the decimal style, not null

    - #### getZeroDigit

          public char getZeroDigit​()

      Gets the character that represents zero.

      The character used to represent digits may vary by culture. This method specifies the zero character to use, which implies the characters for one to nine.

      Returns:
        the character for zero

    - #### withZeroDigit

          public DecimalStyle withZeroDigit​(char zeroDigit)

      Returns a copy of the info with a new character that represents zero.

      The character used to represent digits may vary by culture. This method specifies the zero character to use, which implies the characters for one to nine.

      Parameters:
