Pure Virtual Template Method

Question

Pure virtual templates are not allowed in c++.

In the code I posted is a base class for general math behaviors which should contain basic pure virtual methods which then get inheritanced into different specific classes (atm there is just a binary one, but just imagine there is another numberbase ^^)
How can I make templates for the arguments?
The different return types will be solved with a member variable and a get method.

Answer 1

template as argument example:

template <int A>
void fung()
{
std::cout << A;
}

int main(){fung<10>();}
