/**
 * \file
 * \brief C API: UNumberingSystem, information about numbering systems
 *
 * Defines numbering systems. A numbering system describes the scheme by which 
 * numbers are to be presented to the end user. In its simplest form, a numbering
 * system describes the set of digit characters that are to be used to display
 * numbers, such as Western digits, Thai digits, Arabic-Indic digits, etc., in a
 * positional numbering system with a specified radix (typically 10).
 * More complicated numbering systems are algorithmic in nature, and require use
 * of an RBNF formatter (rule based number formatter), in order to calculate
 * the characters to be displayed for a given number. Examples of algorithmic
 * numbering systems include Roman numerals, Chinese numerals, and Hebrew numerals.
 * Formatting rules for many commonly used numbering systems are included in
 * the ICU package, based on the numbering system rules defined in CLDR.
 * Alternate numbering systems can be specified to a locale by using the
 * numbers locale keyword.
