That is, "0.00" alone is equivalent to "0.00;-0.00". * <P> * The grouping separator is commonly used for thousands, but in some * countries for ten-thousands. The interval is a constant number of * digits between the grouping characters, such as 100,000,000 or 1,0000,0000. * If you supply a pattern with multiple grouping characters, the interval * between the last one and the end of the integer is the one that is * used. So "#,##,###,####" == "######,####" == "##,####,####". * <P> * This class only handles localized digits where the 10 digits are * contiguous in Unicode, from 0 to 9. Other digits sets (such as * superscripts) would need a different subclass. */ class U_I18N_API DecimalFormatSymbols : public UObject { public: /** * Constants for specifying a number format symbol. * @stable ICU 2.0 */ enum ENumberFormatSymbol { /** The decimal separator */ kDecimalSeparatorSymbol, /** The grouping separator */ kGroupingSeparatorSymbol, /** The pattern separator */ kPatternSeparatorSymbol, /** The percent sign */ kPercentSymbol, /** Zero*/ kZeroDigitSymbol, /** Character representing a digit in the pattern */ kDigitSymbol, /** The minus sign */ kMinusSignSymbol, /** The plus sign */ kPlusSignSymbol, /** The currency symbol */ kCurrencySymbol, /** The international currency symbol */ kIntlCurrencySymbol, /** The monetary separator */ kMonetarySeparatorSymbol, /** The exponential symbol */ kExponentialSymbol, /** Per mill symbol - replaces kPermillSymbol */ kPerMillSymbol, /** Escape padding character */ kPadEscapeSymbol, /** Infinity symbol */ kInfinitySymbol, /** Nan symbol */ kNaNSymbol, /** Significant digit symbol * @draft ICU 3.0 */ kSignificantDigitSymbol, /** count symbol constants */ kFormatSymbolCount }; /** * Create a DecimalFormatSymbols object for the given locale. * * @param locale The locale to get symbols for. * @param status Input/output parameter, set to success or * failure code upon return. * @stable ICU 2.0 */ DecimalFormatSymbols(const Locale& locale, UErrorCode& status); /** * Create a DecimalFormatSymbols object for the default locale. * This constructor will not fail.
