COUPNUM(Settlement, Maturity, Frequency, Basis)

Where $Settlement$ is the security's settlement date (a date when coupon or a bond is purchased),
$Maturity$ is the security's maturity date (a date when coupon or a bond expires),
$Frequency$ is the number of coupon payments per year, and
$Basis$ is the type of day count basis to use.

COUPNUM() calculates the number of coupons to be paid between the settlement date and the maturity date.
