class template Convert which can convert itself to any data type

[loves_oi]

template<class T>
class Convert
{   
   T data;
public: 
   Convert(const T& tData = T()) : data(tData)
   { }

   template<class C>   
   bool IsEqualTo( const C& other ) const      
   {        
       return data == other;   
   }
};

template<class T>
operator T() const
{
    return data;
} 

Convert<int> IntData(40);
float FloatData;
double DoubleData;

FloatData = IntData;
DoubleData = IntData;

Convert<int>::operator<float> float();
Convert<int>::operator<double> double();

) ----------------------------------------------------
Why do we use operator? Is float and double function names below?

Convert<int>::operator<float> float();
Convert<int>::operator<double> double();

Thanks in advance
