%% R8POLY_VALUE_HORNER evaluates a polynomial using Horner's method.
%
%  Discussion:
%
%    The polynomial 
%
%      p(x) = c0 + c1 * x + c2 * x^2 + ... + cm * x^m
%
%    is to be evaluated at the value X.

%
%  Input:
%
%    integer M, the degree.
%
%    real C(M+1), the polynomial coefficients.  
%    C(I) is the coefficient of X^(I-1).
%
%    real X, the evaluation point.
%
%  Output:
%
%    real VALUE, the polynomial value.
%
  value = c(m+1);
  for i = m : -1 : 1
    value = value * x + c(i);
