[convert] coversion between strings with different locales

Hi,

I wanted to see how we can convert a double from a locale to another locale?
Should I write

double d =convert<string>::from(convert<double>::from(str)(_locale=f))(_locale=t);

or I need

double d = convert<double>::from(str)(_locale=f);
convert<string>::from(d)(_locale=d);

Or it si a better way?

Best,
