def roots(self, discontinuity=True, extrapolate=None) 

Description

roots.__doc__

        Find real roots of the the piecewise polynomial.

        Parameters
        ----------
        discontinuity : bool, optional
            Whether to report sign changes across discontinuities at
            breakpoints as roots.
        extrapolate : {bool, 'periodic', None}, optional
            If bool, determines whether to return roots from the polynomial
            extrapolated based on first and last intervals, 'periodic' works
            the same as False. If None (default), use `self.extrapolate`.

        Returns
        -------
        roots : ndarray
            Roots of the polynomial(s).

            If the PPoly object describes multiple polynomials, the
            return value is an object array whose each element is an
            ndarray containing the roots.
