I wonder whether Padé approximants are well known by this kind of researcher. E.g. http://www-labs.iro.umontreal.ca/~mignotte/IFT2425/Documents/EfficientApproxi

  Numerical analysts are definitely familiar. Library authors may not be unless they took a course in function approximation. Personally I prefer chebyshev approximants like chebfun but pade are really good at the cost of a division.

    A math library implementor will generally be familiar with at least minimax and Chebyshev approximations, and generally Padé and Carathéodory-Fejér approximations as well. (Source: I implemented math libraries for a decade. We used all of these frequently.)
