    Comment/Request
    I noticed that the numerical result for the Jacobi polynomial (section special functions in Professional) with n=1, alpha=4 and beta=9 at x=-0.5 is given by -6.249999931. Analytically it is equal to -6.25 .
    Is there a possibility to increase the number of digits in the calculation such that the exact value is better approximated? Note that the problem only arose at this specific value of x= -1/2. The Keisan-calculated values of this polynomial for x= -1, 0, +1/2 and +1 were equal to the analytic value given by (5/2)(3x-1).

    Thank you for your advice.
    We have fixed it.
