galois.typing.PolyLike¶

A Union representing objects that can be coerced into a polynomial.

Union

• int: A polynomial in its integer representation, see Int(). The Galois field must be known from context.

# Known from context
In [1]: GF = galois.GF(3)

In [2]: galois.Poly.Int(19, field=GF)
Out[2]: Poly(2x^2 + 1, GF(3))

• str: A polynomial in its string representation, see Str(). The Galois field must be known from context.

In [3]: galois.Poly.Str("2x^2 + 1", field=GF)
Out[3]: Poly(2x^2 + 1, GF(3))

• ArrayLike: An array of polynomial coefficients in degree-descending order. If the coefficients are not Array, then the Galois field must be known from context.

In [4]: galois.Poly([2, 0, 1], field=GF)
Out[4]: Poly(2x^2 + 1, GF(3))

In [5]: galois.Poly(GF([2, 0, 1]))
Out[5]: Poly(2x^2 + 1, GF(3))

• Poly: A previously-created Poly object. No coercion is necessary.
