Description (last modified by )
Even though
sage: MPC = MPComplexField(128) sage: MPC.is_commutative() True
MPC is not in commutative rings:
sage: MPC = MPComplexField(128) sage: P.<x> = PolynomialRing(ZZ, 'x') sage: p = x^3-5*x+1 sage: p.change_ring(MPC)
gives an error
TypeError: Base ring Complex Field with 128 bits of precision must be a commutative ring.
