A simple sizeof(strinstream) gives 140 bytes. Also it's a buffered stream which is too much for a simple number conversion. :) Well this IMO. ;) stringstream is a heavy class to be used just for number conversion.

There is still a more better approach using the boost conversion library. You can also use boost::lexical_cast for the same purpose. #include std::string value = "123.456"; float f = boost::lexical_cast(value); The additional benefit is that when you use stringstream to convert an incorrect number (e.g if the string is "abc.def" and you try to convert it to number), you will get a wrong result. boost::lexical_cast throws a boost::bad_lexical_cast exception when the conversion may not succeed. http://www.boost.org/doc/libs/1_36_0/libs/conversion/lexical_cast.htm std::stringstream is definitely better over sprintf.

There is still a more better approach using the boost conversion library.

You can also use boost::lexical_cast for the same purpose.

#include

std::string value = “123.456″;
float f = boost::lexical_cast(value);

The additional benefit is that when you use stringstream to convert an incorrect number (e.g if the string is “abc.def” and you try to convert it to number), you will get a wrong result.

boost::lexical_cast throws a boost::bad_lexical_cast exception when the conversion may not succeed.
