 #include <iostream>
 #include <boost/multiprecision/cpp_dec_float.hpp>
 typedef boost::multiprecision::number<
 boost::multiprecision::cpp_dec_float< 30, boost::int16_t > > money_t;
 int main( int argc, char * * argv )
 {
     money_t a( 7 );
     money_t b( 7 );
     std::cout << std::numeric_limits< money_t >::infinity( ) - ( a + b )
 << std::endl;
