/**
 * \file
 * \brief C-compatible API for localized number formatting; not recommended for C++.
 *
 * This is the C-compatible version of the NumberFormatter API introduced in ICU 60. 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 resolve conflicts between maximum fraction digits and maximum
 * significant digits.
 *
 * There are two modes, RELAXED and STRICT:
 *
 * - RELAXED: Relax one of the two constraints (fraction digits or significant digits) in order
 *   to round the number to a higher level of precision.
 * - STRICT: Enforce both constraints, resulting in the number being rounded to a lower
 *   level of precision.
 *
 * The default settings for compact notation rounding are Max-Fraction = 0 (round to the nearest
 * integer), Max-Significant = 2 (round to 2 significant digits), and priority RELAXED (choose
 * the constraint that results in more digits being displayed).
 *
 * Conflicting *minimum* fraction and significant digits are always resolved in the direction that
 * results in more trailing zeros.
 *
 * Example 1: Consider the number 3.141, with various different settings:
 *
 * - Max-Fraction = 1: "3.1"
 * - Max-Significant = 3: "3.14"
 *
 * The rounding priority determines how to resolve the conflict when both Max-Fraction and
 * Max-Significant are set. With RELAXED, the less-strict setting (the one that causes more digits
 * to be displayed) will be used; Max-Significant wins. With STRICT, the more-strict setting (the
 * one that causes fewer digits to be displayed) will be used; Max-Fraction wins.
 *
 * Example 2: Consider the number 8317, with various different settings:
 *
 * - Max-Fraction = 1: "8317"
 * - Max-Significant = 3: "8320"
 *
 * Here, RELAXED favors Max-Fraction and STRICT favors Max-Significant. Note that this larger
 * number caused the two modes to favor the opposite result.
