[boost] lexical_cast error with double?

This may have been posted before, but I did not see it or the solution.

This code:
double d = 72.35
std::string = boost::lexical_cast<std::string>(d);

Results in the string 72.3499999999999999999
However printf("%f\n", d);
Results in 72.350000

Any reason for this - or more importantly, any way to fix it and prevent
it happening again?
