{
   CCY money;

   money.HighPart = (long) (parm->p[0].val.ev_real*10000 / pow(2,32));
   
   money.LowPart = (unsigned long) ((parm->p[0].val.ev_real - (double) (money.HighPart * pow(2,32)/10000.0)) *10000);
   
   _RetCurrency(money,25);
}

FoxInfo myFoxInfo[] = {
   {"XNTOM", (FPFI) retcurr, 1, "N"}
