15  * \file
16  * \brief C-compatible API for localized number formatting; not recommended for C++.
17  *
18  * This is the C-compatible version of the NumberFormatter API introduced in ICU 60. C++ users should
19  * include unicode/numberformatter.h and use the proper C++ APIs.
20  *
21  * The C API accepts a number skeleton string for specifying the settings for formatting, which covers a
22  * very large subset of all possible number formatting features. For more information on number skeleton
23  * strings, see unicode/numberformatter.h.
24  *
25  * When using UNumberFormatter, which is treated as immutable, the results are exported to a mutable
26  * UFormattedNumber object, which you subsequently use for populating your string buffer or iterating over
27  * the fields.
28  *
29  * Example code:
30  * <pre>
31  * // Setup:
32  * UErrorCode ec = U_ZERO_ERROR;
33  * UNumberFormatter* uformatter = unumf_openForSkeletonAndLocale(u"precision-integer", -1, "en", &ec);
34  * UFormattedNumber* uresult = unumf_openResult(&ec);
35  * if (U_FAILURE(ec)) { return; }
36  *
37  * // Format a double:
38  * unumf_formatDouble(uformatter, 5142.3, uresult, &ec);
39  * if (U_FAILURE(ec)) { return; }
40  *
41  * // Export the string to a malloc'd buffer:
42  * int32_t len = unumf_resultToString(uresult, NULL, 0, &ec);
43  * // at this point, ec == U_BUFFER_OVERFLOW_ERROR
44  * ec = U_ZERO_ERROR;
45  * UChar* buffer = (UChar*) malloc((len+1)*sizeof(UChar));
46  * unumf_resultToString(uresult, buffer, len+1, &ec);
47  * if (U_FAILURE(ec)) { return; }
48  * // buffer should equal "5,142"
49  *
50  * // Cleanup:
51  * unumf_close(uformatter);
52  * unumf_closeResult(uresult);
53  * free(buffer);
54  * </pre>
55  *
56  * If you are a C++ user linking against the C libraries, you can use the LocalPointer versions of these
57  * APIs. The following example uses LocalPointer with the decimal number and field position APIs:
58  *
59  * <pre>
60  * // Setup:
61  * LocalUNumberFormatterPointer uformatter(unumf_openForSkeletonAndLocale(u"percent", -1, "en", &ec));
62  * LocalUFormattedNumberPointer uresult(unumf_openResult(&ec));
63  * if (U_FAILURE(ec)) { return; }
64  *
65  * // Format a decimal number:
66  * unumf_formatDecimal(uformatter.getAlias(), "9.87E-3", -1, uresult.getAlias(), &ec);
67  * if (U_FAILURE(ec)) { return; }
68  *
69  * // Get the location of the percent sign:
70  * UFieldPosition ufpos = {UNUM_PERCENT_FIELD, 0, 0};
71  * unumf_resultNextFieldPosition(uresult.getAlias(), &ufpos, &ec);
72  * // ufpos should contain beginIndex=7 and endIndex=8 since the string is "0.00987%"
73  *
74  * // No need to do any cleanup since we are using LocalPointer.
75  * </pre>
