Method Details

init (self, x, *cs, **name_f2product_nonfinites_RESIDUAL)
(Constructor)

New Fpolynomial evaluation of the polynomial sum(cs[i] * x**i for i=0..len(cs)-1).

Arguments:

x - Polynomial argument (scalar, an Fsum or Fsum2Tuple).
cs - Polynomial coeffients (each scalar, an Fsum or Fsum2Tuple), all positional.
name_f2product_nonfinites_RESIDUAL - Optional name=NN (str) and other settings, see class Fsum.

Raises:

OverflowError - Partial 2sum overflow.
TypeError - Invalid x.
ValueError - Non-finite x.

Overrides: object.__init__
