`ppform.``from_bernstein_basis`(bp, extrapolate=None)

  Construct a piecewise polynomial in the power basis from a polynomial in Bernstein basis.

  Parameters: | bp : BPoly A Bernstein basis polynomial, as created by BPoly extrapolate : bool or ‘periodic’, optional If bool, determines whether to extrapolate to out-of-bounds points based on first and last intervals, or to return NaNs. If ‘periodic’, periodic extrapolation is used. Default is True.
