Description

Call Poly to evaluate the polynomial represented by the Coefficients parameter at the point where the variable equals the value of the X parameter. The coefficients are ordered in increasing powers of X, as shown in the following Delphi-like example:

Coefficients[0] + Coefficients[1]*X + ... + Coefficients[N]*(X**N)

Note: In C++, the Coefficients_Size parameter is N, the highest power to which X is raised.
