 floating-point-base

    OpenVMS usage:floating_point
    type:         F_floating, D_floating, G_floating, H_floating
    access:       read only
    mechanism:    by value

    Floating-point base. The floating-point-base argument contains
    the value of the base. For OTS$POWRLU, floating-point-base is
    an F-floating number. For OTS$POWDLU, floating-point-base is a
    D-floating number. For OTS$POWGLU, floating-point-base is a G-
    floating number. For OTS$POWHLU_R3, floating-point-base is an
    H-floating number.

 unsigned-lword-int-exponent

    OpenVMS usage:longword_unsigned
    type:         longword (unsigned)
    access:       read only
    mechanism:    by value

    Integer exponent. The unsigned-lword-int-exponent argument
    contains the value of the unsigned longword integer exponent.
