Estou tentando gerar números aleatórios a partir da distribuição normal usando a multiprecisão do impulso. Posso gerar números aleatórios a partir de distribuições uniformes, mas quando tentei gerar a partir do normal normal, ele relata um erro. Aqui está o código:

(segue deExemplos do impulso, altere mpz_int para cpp_int e mpf_float_50 para cpp_dec_float_50)

#include <boost/multiprecision/cpp_int.hpp>
#include <boost/multiprecision/cpp_dec_float.hpp>
#include <boost/multiprecision/random.hpp>
#include <boost/multiprecision/number.hpp>

int main()
{
   using namespace boost::multiprecision;
   using namespace boost::random;

   uniform_01<cpp_dec_float_50> uf;
   normal_distribution<cpp_dec_float_50> n01(0.0, 1.0);
   independent_bits_engine<mt19937, 50L*1000L/301L, cpp_int> gen;

   std::cout << std::setprecision(50);
   for(unsigned i = 0; i < 1; ++i) {
      std::cout << uf(gen) << std::endl;
      std::cout << n01(gen) << std::endl;
   }
   return 0;
}

No entanto, posso gerar números aleatórios a partir de distribuições uniformes, mas quando tentei gerar a partir do normal padrão, ele mostra:

g ++ -I / ~ / boost / boost_1_58_0 -O0 -g3 -Wall -c -fmessage-length = 0 -MMD -MP -MF "test_boost.d" -MT "test_boost.d" -o "test_boost.o" ". ./test_boost.cpp "

boost / boost_1_58_0 / boost / random / detail / uniform_int_float.hpp: 63: erro:static_cast inválido do tipo 'boost :: multiprecision :: detail :: expression>, (boost :: multiprecision :: expression_template_option) 1u>, boost :: multiprecision :: number>, (boost :: multiprecision :: expression_template_option) 1u>, void, void> 'para digitar' int sem assinatura longa '

Eu uso o sistema linux gcc versão 4.4.7 e 64 bits. Muito obrigado.

(Também tentei usar o exemplo do impulso para gerar números aleatórios, mas tenho muitos erros simplesmente por incluir, como:erro: 'struct boost :: multiprecision :: backends :: gmp_int' não possui nenhum membro chamado 'data')

Eu mudei um pouco o código:

#include <boost/multiprecision/random.hpp>
#include <boost/random.hpp>
#include <boost/multiprecision/cpp_int.hpp>
#include <boost/multiprecision/cpp_dec_float.hpp>

int main() {
    namespace mp = boost::multiprecision;

    boost::uniform_01<mp::cpp_dec_float_50> uf;
    boost::normal_distribution<mp::cpp_dec_float_50> n01(0.0, 1.0);

    boost::random::independent_bits_engine<boost::mt19937, 50L * 1000L / 301L, mp::number<mp::cpp_int::backend_type, mp::et_off> > gen;

    std::cout << std::setprecision(50);
    for (unsigned i = 0; i < 10; ++i) {
        std::cout << uf(gen) << std::endl;
        std::cout << n01(gen) << std::endl;
    }
    return 0;
}
