Hi is their anyway for boost to allow only explicit conversion... like class MyInt { // some code inside.... operator int() {} }; myIntCalc(int, int); MyInt a, b; f = myInt(a, b); // compile error no implicit conversion. int x = boost::numeric_cast<int>(a); // k allow int y = static_cast<int>(b); // k allow.

Why not just use a method?
like class MyInt { // some code inside.... int to_int() const; };
myIntCalc(int, int);
MyInt a, b; f = myInt(a, b); // compile error no implicit conversion.
int x = boost::numeric_cast<int>(a); // k allow
int x = a.to_int();
cause i want to use it in a generic function and other numeric type your_int
may or not have to_int...
