The functions described here evaluate the polynomial
c[0] + c[1] x + c[2] x^2 + \dots + c[len-1] x^{len-1} using
Horner's method for stability. Inline versions of these functions are used when HAVE_INLINE
is defined.
This function evaluates a polynomial with real coefficients for the real variable x.
This function evaluates a polynomial with real coefficients for the complex variable z.
This function evaluates a polynomial with complex coefficients for the complex variable z.
