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.
}}}
