#include <codecogs/finance/banking/coupondaystoset.h>

using namespace Finance::Banking;

int couponDaysToSet(int sett, int mat, Finance::Banking::YearlyFreq freq, Finance::Banking::YearBasis basis=yb_USA)

This function computes the number of days from the beginning of the current coupon period to the settlement. The year basis is taken into account. This function is equivalent to the Microsoft Excel function COUPDAYBS.

For a security, the settlement date is the date after issue when the security is traded to the buyer. The maturity date is the date at which the security expires.

#include <stdio.h>

#include <codecogs/units/date/date.h>
#include <codecogs/units/date/dateymd.h>
#include <codecogs/finance/banking/coupondaystoset.h>

int main(void)
{
  int settDate=Units::Date::date(1998, 1, 25);
  int maturityDate=Units::Date::date(1999, 11, 15);

  int days=Finance::Banking::couponDaysToSet(settDate,
                                             maturityDate,
                                             Finance::Banking::yf_SemiAnnual,
                                             Finance::Banking::yb_Act);
  int y, m, d;
  
  Units::Date::dateYMD(settDate, y, m, d);
  printf("settlement=%i/%i/%i\n", y, m, d);
  
  Units::Date::dateYMD(maturityDate, y, m, d);
  printf("maturity=%i/%i/%i\n", y, m, d);
  
  printf("days to settlement=%i\n", days);

  return 0;
