money_get::get
Extracts a numerical value from a character sequence that represents a monetary value.
iter_type get(
iter_type _First,
iter_type _Last,
bool _Intl,
ios_base& _Iosbase,
ios_base::iostate& _State,
long double& _Val
) const;
iter_type get(
iter_type _First,
iter_type _Last,
bool _Intl,
ios_base& _Iosbase,
ios_base::iostate& _State,
string_type& _Val
) const;
Parameters
_First
Input iterator addressing the beginning of the sequence to be converted._Last
Input iterator addressing the end of the sequence to be converted._Intl
A Boolean value indicating the type of currency symbol expected in the sequence: true if international, false if domestic._Iosbase
A format flag which when set indicates that the currency symbol is optional; otherwise, it is required_State
Sets the appropriate bitmask elements for the stream state according to whether the operations succeeded._Val
A string storing the converted sequence.
Return Value
An input iterator addressing the first element beyond the monetary input field.
Remarks
Both member functions return do_get(_First, _Last, _Intl, _Iosbase, _State, _Val).
Example
// money_get_get.cpp
// compile with: /EHsc
#include <locale>
#include <iostream>
#include <sstream>
using namespace std;
int main( )
{
locale loc( "german_germany" );
basic_stringstream< char > psz;
psz << use_facet<moneypunct<char, 1> >(loc).curr_symbol() << "-1.000,56";
basic_stringstream< char > psz2;
psz2 << "-100056" << use_facet<moneypunct<char, 1> >(loc).curr_symbol();
ios_base::iostate st = 0;
long double fVal;
psz.flags( psz.flags( )|ios_base::showbase );
// Which forced the READING the currency symbol
psz.imbue(loc);
use_facet < money_get < char > >( loc ).
get( basic_istream<char>::_Iter( psz.rdbuf( ) ),
basic_istream<char>::_Iter( 0 ), true, psz, st, fVal );
if ( st & ios_base::failbit )
cout << "money_get(" << psz.str( ) << ", intl = 1) FAILED"
<< endl;
else
cout << "money_get(" << psz.str( ) << ", intl = 1) = "
<< fVal/100.0 << endl;
use_facet < money_get < char > >( loc ).
get(basic_istream<char>::_Iter(psz2.rdbuf( )),
basic_istream<char>::_Iter(0), false, psz2, st, fVal);
if ( st & ios_base::failbit )
cout << "money_get(" << psz2.str( ) << ", intl = 0) FAILED"
<< endl;
else
cout << "money_get(" << psz2.str( ) << ", intl = 0) = "
<< fVal/100.0 << endl;
};
Sample Output
If you run Windows 2000 or earlier, you will get this output:
money_get(DEM-1.000,56, intl = 1) = -1000.56
money_get(-100056DM, intl = 0) = -1000.56
If you run Windows XP, you will get this output:
money_get(EUR-1.000,56, intl = 1) = -1000.56
money_get(-100056EUR, intl = 0) = -1000.56
