C++11 includes std::stoi, why not std::itos?

Question

I noticed to my glee that C++11 has a std stoX family of functions for easily unpacking ints/floats/longs whatever from strings. I'm surprised however, that the opposite isn't implemented. Why didn't the standards committee include a std::itos family of functions for going from ints/floats/whatever to strings?

Answer 1

I was mistaken, there is a set of "stoX" functions, they are all just named "to_string". Each to_string is overloaded to take a different basic type, ie

string to_string(float f);
string to_string(int f);
