CouponDaysInPeriod

 
intcouponDaysInPeriodintsett
intmat
Finance::Banking::YearlyFreqfreq
Finance::Banking::YearBasisbasis = yb_USA )
Calculate the number of days in the coupon period that contains the settlement date. The number of days returned depends on the year basis specified:

For yb_USA, yb_EU and yb_Act360 the returned value is:

Where freq is the number of times per year the payment is made (1 for yf_Annual, 2 for yf_SemiAnnual or 4 for yf_Quarterly).

For yb_Act365 the returned value is: (Using integer division)

Finally, for yb_Act, the exact number of days between the two dates (taking into account leap years) is returned.

Example 1

#include <stdio.h>
 
#include <codecogs/units/date/date.h>
#include <codecogs/units/date/dateymd.h>
#include <codecogs/finance/banking/coupondaysinperiod.h>
 
int main(void)
{
  int settDate=Units::Date::date(1998, 1, 25);
  int maturityDate=Units::Date::date(1999, 11, 15);
  int days=Finance::Banking::couponDaysInPeriod(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 in period=%i\n", days);   return 0; }
Output:
settlement=1998/1/25
maturity=1999/11/15
days in period=181
