I said that I am not sure if boost::variant supports __int128 because I had
difficulties in compiling this code :
1. #include <boost/variant.hpp>
2. #include <string>
3. #include <iostream>
4. std::ostream& operator<<(std::ostream& o, const __int128& x) { if (x
== std::numeric_limits<__int128>::min()) return o <<
"-170141183460469231731687303715884105728"; if (x < 0) return o << "-" <<
-x; if (x < 10) return o << (char)(x + '0'); return o << x / 10 << (char)
(x % 10 + '0'); }
5. int main()
6. {
7. boost::variant<__int128, char, std::string> v;
8. v = 56;
9. v = 'Y';
10. __int128 d=12;
11. std::cout <<d << '\n';
12. std::cout << v << '\n';
13. v = "Yashaswi raj";
14. std::cout << v << '\n';
15. }
If u replace __int128 with int in the variant variable, it seems to work
just fine...
