evaluationdate = a string containing a date specification in a format recognized by ParseDate or a Date data structure -- This option specifies the evaluation date. By default this is set to the global evaluation date (see EvaluationDate ).

The CleanPrice command computes the clean price of a bond, given its yield. Clean price does not include any accrued interest that has accumulated since the last coupon payment.

The parameter bond is either a fixed coupon bond or floating rate bond . The parameter yield is the desired yield.
