Maybe this idea helps:

#include <iostream>
using namespace std;

struct Null { Null operator+() const { return Null(); } } null;

template< typename T >
T operator+( const T& v, const Null& ) { return v; }

template< typename T >
T operator%( const T& v, const Null& ) { return v / 100; }

#define TEST( X ) (X+null)

int main()
{
  cout << TEST( 0.5% ) << endl
       << TEST( 0.05 ) << endl;
}
