C++ users should + * include unicode/numberformatter.h and use the proper C++ APIs. + * + * The C API accepts a number skeleton string for specifying the settings for formatting, which covers a + * very large subset of all possible number formatting features. For more information on number skeleton + * strings, see unicode/numberformatter.h. + * + * When using UNumberFormatter, which is treated as immutable, the results are exported to a mutable + * UFormattedNumber object, which you subsequently use for populating your string buffer or iterating over + * the fields. + * + * Example code: + * <pre> + * // Setup: + * UErrorCode ec = U_ZERO_ERROR; + * UNumberFormatter* uformatter = unumf_openForSkeletonAndLocale(u"precision-integer", -1, "en", &ec); + * UFormattedNumber* uresult = unumf_openResult(&ec); + * if (U_FAILURE(ec)) { return; } + * + * // Format a double: + * unumf_formatDouble(uformatter, 5142.3, uresult, &ec); + * if (U_FAILURE(ec)) { return; } + * + * // Export the string to a malloc'd buffer: + * int32_t len = unumf_resultToString(uresult, NULL, 0, &ec); + * // at this point, ec == U_BUFFER_OVERFLOW_ERROR + * ec = U_ZERO_ERROR; + * UChar* buffer = (UChar*) malloc((len+1)*sizeof(UChar)); + * unumf_resultToString(uresult, buffer, len+1, &ec); + * if (U_FAILURE(ec)) { return; } + * // buffer should equal "5,142" + * + * // Cleanup: + * unumf_close(uformatter); + * unumf_closeResult(uresult); + * free(buffer); + * </pre> + * + * If you are a C++ user linking against the C libraries, you can use the LocalPointer versions of these + * APIs. The following example uses LocalPointer with the decimal number and field position APIs: + * + * <pre> + * // Setup: + * LocalUNumberFormatterPointer uformatter(unumf_openForSkeletonAndLocale(u"percent", -1, "en", &ec)); + * LocalUFormattedNumberPointer uresult(unumf_openResult(&ec)); + * if (U_FAILURE(ec)) { return; } + * + * // Format a decimal number: + * unumf_formatDecimal(uformatter.getAlias(), "9.87E-3", -1, uresult.getAlias(), &ec); + * if (U_FAILURE(ec)) { return; } + * + * // Get the location of the percent sign: + * UFieldPosition ufpos = {UNUM_PERCENT_FIELD, 0, 0}; + * unumf_resultNextFieldPosition(uresult.getAlias(), &ufpos, &ec); + * // ufpos should contain beginIndex=7 and endIndex=8 since the string is "0.00987%" + * + * // No need to do any cleanup since we are using LocalPointer. + * </pre> + */ + +/** + * An enum declaring how to render units, including currencies.
