public abstract class PluralRules
extends Object

Helps to determine the plural category for a given number of units.

The predefined rules for any given language are based on CLDR-version 26 but can be overridden if necessary. The source data of the underlying algorithms to determine the plural category can be found in CLDR-repository-file "core.zip" along the path "common/supplemental/plurals.xml" for cardinal numbers and "common/supplemental/ordinals.xml" for ordinal numbers.
