Hello All!

I'm having troubles with this very simple class when I try to overload
the + operand. It runs with shorts expresions: (i.e: a+b+a+b+a+b)
but returns NaN ("Not a Number" numeric comprocesor exception, (DJGPP FAQ
section 11.5)) or hungs... I supouse that the class is well definied because
runs with <int> instead of <double> :-? (My computer is a Pentium MMX)

Can anyone help me?

Thank's for your time!

#include <stdio.h>

class Euro{

private:
   double eurocents;

public:
   Euro(void) {eurocents=0;}
   Euro(double const euros) {eurocents=(euros * 100);}

   double Euros(void) {return(eurocents / 100);}

   Euro operator+ (const Euro &op)
                  {return(Euro((eurocents + op.eurocents) / 100));}
   };

int main (){
   Euro a(1),b(1),sum;
   sum=a+b;
//   sum=a+b+a+b+a+b+a+b+a+b+a+b+a+b+a+b+a+b+a+b+a+b+a+b+a+b+a+b; // It
compiles but :'(
   printf("\nSum: %f",sum.Euros());
}
