HP-92 Simulation Attempt

If N is the number of semi-annual coupons between settlement date and maturity date, then that would always be a whole number, no fractions. If I buy a bond with a maturity date of 15 Aug 2019, then there should be a coupon (interest payment) on 15 Feb and 15 Aug each year, between the settlement date and maturity date. Let's say I put in an order to buy it on 9 March of this year, then the settlement date would normally be 12 March (3 business days later), so I would get my first coupon on 15 Aug 2017 and additional ones on 15 Feb 2018, 15 Aug 2018, 15 Feb 2019 and 15 Aug 2019, so there would be a total of 5 coupons.

I'm not sure about E. It could be one of two things:
1. The number of days between the last coupon date (15 Feb) and my settlement date of
12 March, OR
2. It could be the number of days between my settlement date and the next coupon date
(15 Aug).

Hope this helps a little.
