FNPolyevaluates a polynomial of degreenwhose coefficients are given in the elements ofCat argumentx. The first element inCis the constant term in the polynomial, the second element is the first-degree term (the multiplier ofx), the third element is the second-degree term (the multiplier ofx2), etc.Cmust contain at leastn+1 elements; if it contains more thann+1 elements, the extra elements are ignored.
Errors
FNPolycauses an HTBasic error if its arguments are not of the types listed in the USAGE section, above, or if the arrayChas fewer thann+1 elements.
