I'm sure it's consistent with std::iostream behavior so it's not a bug :(

FWIW, sending the double value to std::cout works as expected: double d = 72.35; std::string s = boost::lexical_cast<std::string>(d); printf("%s\n", s.c_str()); // prints 72.34999999999999 std::cout << d << std::endl; // prints 72.35 Reading 72.35 from std::cin works as expected in both cases: double d = 0.0; std::cin >> d; std::string s = boost::lexical_cast<std::string>(d); printf("%s\n", s.c_str()); // prints 72.35 std::cout << d << std::endl; // prints 72.35 (MSVC8) Jon Jon
