std::overflow_error (a derived class from std::runtime_error) is thrown if a 'mathematical overflow occurs'. I did not yet succeed in producing such a mathematical overflow.


#include <cmath>

#include <iostream>

#include <stdexcept>



int main()

{

  try

  {

    //Too bad std::fmod does not throw std::overflow_error :-(

    const double x = std::fmod(1.0,0.0);

    std::cout << x;

  }

  catch (std::overflow_error& e)

  {

    //Will not get here :-(

    std::cout << e.what();

  }

}

Screen output:
