-Name __poly - generates a polynomial from arguments
-
-Usage double __poly ( double x, int n, const double* c );
-
-Prototype in math.h
-
-Description __poly generates a polynomial in x, of degree n, with
- coefficients c[0], c[1], ..., c[n]. For example, if n=4,
- the generated polynomial is
-
- c[4]*x^4 + c[3]*x^3 + c[2]*x^2 + c[1]*x + c[0]
-
- The polynomial is calculated using Horner's method:
-
- polynom = (..((x*c[n] + c[n-1])*x + c[n-2])..)*x + c[0]
-
-Return value __poly returns the value of the polynomial as evaluated for
- the given x.
- A range error occurs if the result exceeds double range.
