Function Documentation

This function computes the number of days from the settlement date to the next coupon date. The year basis is taken into account.

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.

Example:

#include <stdio.h>
 
#include <codecogs/units/date/date.h>
#include <codecogs/units/date/dateymd.h>
#include <codecogs/finance/banking/coupondaysafterset.h>
 
int main(void)
{
  int settDate=Units::Date::date(1998, 1, 25);
  int maturityDate=Units::Date::date(1999, 11, 15);
 
  int days=Finance::Banking::couponDaysAfterSet(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 after settlement=%i\n", days);
 
  return 0;
}

Output:

settlement=1998/1/25
maturity=1999/11/15
days after settlement=110
