    This function returns the equivalent yield for a Treasury bill (or T-bill).




    This function has these arguments:

    Argument Description
    settle Settlement date for the Treasury bill
    mature Maturity date for the Treasury bill
    discount Discount rate for the Treasury bill


    This function returns a #VALUE! error when settle or mature is invalid. Settle and mature are truncated to integers. If discount is less than or equal to 0, a #NUM! error is returned. If settle is greater than mature or if mature is more than one year after settle, a #NUM! error is returned. This function is calculated as (365 x rate)/(360-(rate x DSM)), where DSM is the number of days between settle and mature computed according to the 360 days per year basis.
