Re: I'm having trouble understanding overloaded operators

Hello, I am trying to understand overloaded operators but am getting
confused as to how I can provide a conversion from my number class and=

the scalar types?

If I create a class that represents a fictional number type, I
understand that I can create an overloaded assignment operator that
will accept long int for example. What I do not understand is how I
create an assignment operator to do the reverse, i.e. assign my
numeric class value to the scalar long int?

class myLong
{
        public:
                myLong()
                        : val(0)
                {
                };

                myLong(long val)
                        : val(val)
                {
                };

                myLong(const myLong& that)
                        : val(that.val)
                {
                };

                myLong& operator=(const myLong& that=

                {

                        if (this != &that)
                        {
                                this->=

                        }

                        return(*this);
                };

                long getVal()
                {
                        return(val);
                };

        private:
                long val;

};

So this works for something like

myLong mylong;
mylong = 42;
long scalarLong = mylong.getVal();
myLong newLong = mylong;
scalarLong++;
mylong = scalarLong;

But how do I do something like this

myLong myLongTest;
myLongTest = 1;
long scalarLong = myLongTest;

I do not know how to code this reverse assignment. I tried a few ways
but failed dismally.
