If @basis is omitted, US 30/360 is applied. If issue date or settlement date is not valid, ACCRINT returns NUM! error.If @rate or @par is zero or negative, ACCRINT returns NUM! error.If @basis < 0 or @basis > 4, ACCRINT returns NUM! error. If issue date is after maturity date or they are the same, ACCRINT returns NUM! error.
