C++ String to double conversion

Say I have a number in a string (Y) in the form "XXX.XXXXX". It seems that (char*)Y.data() stops at the decimal point. Is there any way to change the delimiter settings so that it gets the decimal too?

Code:
#include <sstream>
#include <string>
int main()
{
   std::string str("123.123");
   std::stringstream sstr;
   sstr <<str;
   double d;
   sstr >>d;
}
Hmm have I misunderstood your question?
You have a string and want to copy it to another string?

Using your code it tells me that there is no such file when I try to include <stringstream> and compile using g++. What's up with that?
