 * If either Yield or Coupon is less than 0 then the function returns an error value.
 * If either Settlement or Maturity are not valid dates then the function returns an value(#VALUE!) error.
 * If Settlement date is after the Maturity date then the function returns an error value.
 * If Frequency, and Basis are non-integer values, then the function uses their floor value, i.e. they are truncated to an integer value.
 * After truncation if Frequency is any number except 1,2 or 4, then the function returns an error value.
 * After truncation if Basis is ny number except 0,1,2,3,4 or missing(passed as empty argument or not passed at all),then the function will return an error value.
