C++ combination of stod and stoi?

Is there a combination of stod and stoi? So that I could have a string s = "0.1 1 2.3 3 4.4" and stod_stoi_combined(s) would extract me doubles and ints depending on what the input is?

There is no such combination in the standard library.

There can be no such combination, because the return type of a function cannot depend on the value of the parameter. The return type is always the same, not sometimes int and other times double.

You could possibly write a function that returns std::variant<int, double>. Note that std::variant isn't part of the standard library until the upcoming C++17, so if you cannot wait, you'll have to use a third party alternative.
