No. The problem is that 'x' is a symbol and you want it treated
as polynomial. In Spad (in contract to FriCAS command line)
there is no automatic conversion of symbols to polynomials.
Instead one normally uses 'monomial' function. In your case:
)abbrev package TEST TestPackage
TestPackage(x) : Exports == Implementation where
x : Symbol
Exports == with
f : NonNegativeInteger -> UnivariatePolynomial(x, Fraction
Integer)
Implementation == add
f(d) == monomial(1, d)
Ah, thanks Waldek, that explains it.
