Purpose
Returns a floating point value that is an approximation of a polynomial formed from the specified one-dimensional array expression. The returned value has the same attributes as the first argument.
Parameters
x is an array expression, and y is an element expression.
Description
x must be real float and y is converted to the attributes of x, if necessary.
If x has lower bound 0 and upper bound n, the result is a classic polynomial of degree n in y with coefficients given by x: x(0) + x(1)*y + x(2)*y**2 + ... + x(n)*y**n.
In the general case, where x has lower bound m and upper bound n, the result is the polynomial x(m) + x(m+1)*y + x(m+2)*y**2 + ... + x(n)*y**(n-m)
