Method degree

numpy/polynomial/_polybase.py:670–702

The degree of the series. Returns ------- degree : int Degree of the series, one less than the number of coefficients. Examples -------- Create a polynomial object for ``1 + 7*x + 4*x**2``: >>> np.polynomial.set_default_printsty

(self)

        return self.__class__(self.coef, self.domain, self.window, self.symbol)

        degree : int
            Degree of the series, one less than the number of coefficients.

        Examples
        --------

        Create a polynomial object for ``1 + 7*x + 4*x**2``:

        >>> np.polynomial.set_default_printstyle("unicode")
        >>> poly = np.polynomial.Polynomial([1, 7, 4])
        >>> print(poly)
        1.0 + 7.0·x + 4.0·x²
        >>> poly.degree()
        2

        Note that this method does not check for non-zero coefficients.
        You must trim the polynomial to remove any trailing zeroes:

        >>> poly = np.polynomial.Polynomial([1, 7, 0])
        >>> print(poly)
        1.0 + 7.0·x + 0.0·x²
        >>> poly.degree()
        2
        >>> poly.trim().degree()
        1
