Description
Projective equality is returning false positives for ComplexIntervalField? points because it is doing a negative check not a positive check
R.<x>=PolynomialRing(QQ) r=(x^2x3).polynomial(x).roots(ComplexIntervalField(),multiplicities=False) P.<x,y>=ProjectiveSpace(ComplexIntervalField(),1) P1=P(r[0],1) H=End(P) f = H([x^23*y^2,y^2]) Q1=f(P1) Q1==P1, Q1[0]==P1[0]
This is likely an issue for both points and morphisms.

Just two minor typos in projective_point __eq__

, projective is spelled wrong

Looks good. I can't find any additional typos, and the doctests pass
