NumberFormat

The NumberFormat filter can be used to return locale-specific number and percentage strings. It extends the NumberParse filter, which acts as wrapper for the NumberFormatter class within the Internationalization extension (Intl).

Supported Options

The following options are supported for NumberFormat:

NumberFormat([ string $locale [, int $style [, int $type ]]])

• $locale: (Optional) Locale in which the number would be formatted (locale name, e.g. en_US). If unset, it will use the default locale (Locale::getDefault())

  Methods for getting/setting the locale are also available: getLocale() and setLocale()

• $style: (Optional) Style of the formatting, one of the format style constants. If unset, it will use NumberFormatter::DEFAULT_STYLE as the default style.

  Methods for getting/setting the format style are also available: getStyle() and setStyle()

• $type: (Optional) The formatting type to use. If unset, it will use NumberFormatter::TYPE_DOUBLE as the default type.

  Methods for getting/setting the format type are also available: getType() and setType()
