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
