* \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 UCAL_DECIMAL to get the normal number format for that country.
|
|
* There are other static options available. Use UCAL_CURRENCY
|
|
* to get the currency number format for that country. Use UCAL_PERCENT
|
|
* to get a format for displaying percentages. With this format, a
|
|
* fraction from 0.53 is displayed as 53%.
|
|
* <P>
|
|
* You can also control the display of numbers with such function as
|
|
* unum_getAttribues() and unum_setAtributes(). where in you can set the
|
|
* miminum fraction digits, grouping used 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().
