ODDLYIELD(s,m,lt,r,pr,rdm,f,b)

• $s$ is the settlement.
• $m$ is the maturity.
• $lt$ is the last coupon date.
• $r$ is the rate of interest.
• $pr$ is the security's price.
• $rdm$ is the security's redemption.
• $f$ is the frequency.
• $b$ is the basis.

Description

• This function gives the yield of a security that pays interest periodically but has an odd last period.
• This function is the inverse function of the OddLPrice function.
• In $ODDLYIELD(s,m,lt,r,pr,rdm,f,b)$, $s$ is the security's settlementDate. It is a Date or DateTime specifying when the security was purchased.
• $m$ is the security's maturity date. This date is after the settlement date specifying when the security matures.
• $lt$ is the date which is specifying when the security has its last payment. This date must be before the settlementDate.
• $r$ is a non-negative number specifying the interest rate for the coupons that the security pays.
• $pr$ is a non-negative number or currency specifying the security’s purchase price per $100 of face value.
• $rdm$ is a number or currency specifying the security’s value at redemption per $100 of face value.
• $f$is is a number specifying the number of coupons per year.
• The supported values are

 1 -annual payments
 2 -semiannual payments
 4 -quarterly.

• $b$ is is an optional number specifying the day basis system to use.
• The following types are supported

Basis	Day count basis
0 or omitted	American 30/360 (default)
1	actual/actual
2	actual/360
3	actual/365
4	European 30/360

• $ODDLYIELD$ is calculated as follows:
• $ODDLYIELD$=
• $A_{i}$ = number of accrued days for the ith, or last, quasi-coupon period within odd period counting forward from last interest date before redemption.
• $DC_{i}$ = number of days counted in the ith, or last, quasi-coupon period as delimited by the length of the actual coupon period.
• $NC$ = number of quasi-coupon periods that fit in odd period; if this number contains a fraction it will be raised to the next whole number.
• $NL_{i}$ = normal length in days of the ith, or last, quasi-coupon period within odd coupon period.
• The date arguments must satisfy the following conditions:

       s(settlement) <lt(last interest) < m(maturity). 

• Also $s$, $m$, $lt$,and $b$ are truncated in to integers.
• This function gives the result as error when

  1.The date arguments s,m and lt are not a valid date.
  2.r<0 or pr<=0
  3.b<0 or b>4
