The Evaluate Polynomials routine (D-floating values) allows
    higher-level language users to evaluate D-floating value
    polynomials.

    D-floating values are not supported in full precision in native
    OpenVMS Alpha and I64 programs. They are precise to 56 bits on
    VAX systems, 53 or 56 bits in translated VAX images, and 53 bits
    in native OpenVMS Alpha and I64 programs.
