Title: Locale dependent digit grouping
Posted by: [EMAIL PROTECTED]
Affected: unotools
Effective from: CWS locales30
*Summary*
--------
#include <unotools/localedatawrapper.hxx>
class LocaleDataWrapper
{
[...]
+ const ::com::sun::star::uno::Sequence< sal_Int32 > getDigitGrouping() const;
[...]
};
#include <unotools/digitgroupingiterator.hxx>
namspace utl {
class DigitGroupingIterator
{
explicit DigitGroupingIterator( const ::com::sun::star::uno::Sequence<
sal_Int32 > & rGroupings );
[...]
};
}
*Description*
-------------
Digit grouping (AKA thousands) in fact may be locale dependent.
Class LocaleDataWrapper now supports a method getDigitGrouping() that
returns a sequence containing a rule for grouping positions. See below
for details. This sequence may be used with the already existing
::rtl::math::doubleToString() method or the new class
DigitGroupingIterator. The LocaleDataWrapper methods getNum() and
getCurr() that get a bUseThousandSep parameter passed internally make
use of the grouping rules, as does the number formatter.
#include <unotools/localedatawrapper.hxx>
class LocaleDataWrapper
{
[...]
/** Obtain digit grouping. The usually known grouping by
thousands (#,###) is actually only one of possible
groupings. Another one, for example, used in India is
group by 3 and then by 2 indefinitely (#,##,###). The
integer sequence returned here specifies grouping from
right to left (!), with a 0 entry designating the end of
rules and the previous value to be repeated indefinitely.
Hence the sequence {3,0} specifies the usual grouping by
thousands, whereas the sequence {3,2,0} specifies Indian
grouping. The sal_Int32* getConstArray() can be passed
directly to the ::rtl::math::doubleToString() methods as
argument for the pGroups parameter. */
