Floor[] Not An Integer?

I'm trying to use some of the NumericalMath approximations such as
MiniMaxApproximation and RationalInterpolation with a function that
includes array references of the form Array[[Floor[x]]].  The function
plots and evaluates just fine but the NumericalMath functions are
reporting the error:

"Part::pspec: Part specification Floor[x] is neither an integer nor a
list of integers."

whereas the documentation states that Floor[x] IS an integer.

What am I missing?

Thanks for any insight.

Cheers, Scott
