Hello.
I learnt today to my dismay that there is in fact no number to string
conversion function in the standard C++ library? I can't do simple
natural things like:
std :: string a ( 2 ) ;
std :: string b ( 2.5 ) ;
without errors at compilation talking about "no matching function for call".
I find it difficult to believe that no-one thought this was necessary
enough to be included in the C++ standard basic_string class.
The three ways out of this problem I got to know:
1. stringstream from std, resulting in somewhat unweildy operations
2. lexical_cast from boost, resulting in dependency on huge boost lib
3. QString from Qt, resulting in depdency on huge Qt lib
Of course stdc++ is also a huge lib, but thought I can expect stdc++ to
be there on more machines than boost or Qt.
So shall I go with std::string and std::stringstream, std::string and
boost::lexical_cast or simply Qt's QString? QString seems most
appealing, but I would listen to your better judgment.
