Description
Function imsl_f_treasury_bill_price computes the price per $100 face value for a Treasury bill.
It is computed using the following:
In the equation above, DSM represents the number of days in the period starting with the settlement date and ending with the maturity date (any maturity date that is more than one calendar year after the settlement date is excluded).

#include <stdio.h>
#include "imsl.h"
void main()
{
struct tm settlement, maturity;
float discount = .05;
float price;
settlement.tm_year = 100;
settlement.tm_mon = 6;
settlement.tm_mday = 1;
maturity.tm_year = 101;
maturity.tm_mon = 6;
maturity.tm_mday = 1;
price = imsl_f_treasury_bill_price (settlement, maturity, discount);
printf ("The price per $100 face value for the T-bill ");
printf ("is $%.2f.\n", price);
}
