Abstract
We shall show that quadrature formulas of double precision, also using evaluation functionals of derivatives of the function instead of evaluation functionals of the function only, exist if the order of the derivatives is prescribed in the form of a certain pyramidal display. This type of Gaussian formulas is derived through an extremal property of certain polynomials extending the extremal property of the classical Gaussian formulas. The results generalize to the multiple node case.
