+ * \file
+ * \brief C API: NumberFormat
+ *
+ * <h2> Number Format C API </h2>
+ *
+ * Number Format C API Provides functions for
+ * formatting and parsing a number. Also provides methods for
+ * determining which locales have number formats, and what their names
+ * are.
+ * <P>
+ * UNumberFormat helps you to format and parse numbers for any locale.
+ * Your code can be completely independent of the locale conventions
+ * for decimal points, thousands-separators, or even the particular
+ * decimal digits used, or whether the number format is even decimal.
+ * There are different number format styles like decimal, currency,
+ * percent and spellout.
+ * <P>
+ * To format a number for the current Locale, use one of the static
+ * factory methods:
+ * <pre>
+ * \code
+ * UChar myString[20];
+ * double myNumber = 7.0;
+ * UErrorCode status = U_ZERO_ERROR;
+ * UNumberFormat* nf = unum_open(UNUM_DEFAULT, NULL, -1, NULL, NULL, &status);
+ * unum_formatDouble(nf, myNumber, myString, 20, NULL, &status);
+ * printf(" Example 1: %s\n", austrdup(myString) ); //austrdup( a function used to convert UChar* to char*)
+ * \endcode
+ * </pre>
+ * If you are formatting multiple numbers, it is more efficient to get
+ * the format and use it multiple times so that the system doesn't
+ * have to fetch the information about the local language and country
+ * conventions multiple times.
+ * <pre>
+ * \code
+ * uint32_t i, resultlength, reslenneeded;
+ * UErrorCode status = U_ZERO_ERROR;
+ * UFieldPosition pos;
+ * uint32_t a[] = { 123, 3333, -1234567 };
+ * const uint32_t a_len = sizeof(a) / sizeof(a[0]);
+ * UNumberFormat* nf;
+ * UChar* result = NULL;
+ *
+ * nf = unum_open(UNUM_DEFAULT, NULL, -1, NULL, NULL, &status);
+ * for (i = 0; i < a_len; i++) {
+ * resultlength=0;
+ * reslenneeded=unum_format(nf, a[i], NULL, resultlength, &pos, &status);
+ * result = NULL;
+ * if(status==U_BUFFER_OVERFLOW_ERROR){
+ * status=U_ZERO_ERROR;
+ * resultlength=reslenneeded+1;
+ * result=(UChar*)malloc(sizeof(UChar) * resultlength);
+ * unum_format(nf, a[i], result, resultlength, &pos, &status);
+ * }
+ * printf( " Example 2: %s\n", austrdup(result));
+ * free(result);
+ * }
+ * \endcode
+ * </pre>
+ * To format a number for a different Locale, specify it in the
+ * call to unum_open().
+ * <pre>
+ * \code
+ * UNumberFormat* nf = unum_open(UNUM_DEFAULT, NULL, -1, "fr_FR", NULL, &success)
+ * \endcode
+ * </pre>
+ * You can use a NumberFormat API unum_parse() to parse.
+ * <pre>
+ * \code
+ * UErrorCode status = U_ZERO_ERROR;
+ * int32_t pos=0;
+ * int32_t num;
+ * num = unum_parse(nf, str, u_strlen(str), &pos, &status);
+ * \endcode
+ * </pre>
+ * Use UNUM_DECIMAL to get the normal number format for that country.
+ * There are other static options available. Use UNUM_CURRENCY
+ * to get the currency number format for that country. Use UNUM_PERCENT
+ * to get a format for displaying percentages. With this format, a
+ * fraction from 0.53 is displayed as 53%.
+ * <P>
+ * Use a pattern to create either a DecimalFormat or a RuleBasedNumberFormat
+ * formatter. The pattern must conform to the syntax defined for those
+ * formatters.
+ * <P>
+ * You can also control the display of numbers with such function as
+ * unum_getAttribues() and unum_setAtributes(), which let you set the
+ * miminum fraction digits, grouping, etc.
+ * @see UNumberFormatAttributes for more details
+ * <P>
+ * You can also use forms of the parse and format methods with
+ * ParsePosition and UFieldPosition to allow you to:
+ * <ul type=round>
+ * <li>(a) progressively parse through pieces of a string.
+ * <li>(b) align the decimal point and other areas.
+ * </ul>
+ * <p>
+ * It is also possible to change or set the symbols used for a particular
+ * locale like the currency symbol, the grouping seperator , monetary seperator
+ * etc by making use of functions unum_setSymbols() and unum_getSymbols().
