¥Parameters

返回值

¥Return value

表示指定范围的复数类别的字符串。这可以是 zero、one、two、few、many 或 other 之一，与 LDML 语言复数规则 中指定的本地化语言环境相关。

描述

¥Description

此函数根据 Intl.PluralRules 对象的区域设置和格式选项选择复数类别。

¥This function selects a pluralization category according to the locale and formatting options of an Intl.PluralRules object.

从概念上讲，该行为与获取单个基数或序数的复数规则相同。语言具有一种或多种用于描述范围的形式，并且在给定提供的区域设置和格式选项的情况下，此方法返回适当的形式。英语中只有一种复数形式，例如 "1–10 个苹果"，该方法将返回 other。其他语言可以有多种形式。

¥Conceptually the behavior is the same as getting plural rules for a single cardinal or ordinal number. Languages have one or more forms for describing ranges, and this method returns the appropriate form given the supplied locale and formatting options. In English there is only one plural form, such as "1–10 apples", and the method will return other. Other languages can have many forms.
