| 2019-03-15 09:14:31 +0200 | asked a question | elliptic curve arithmetic without inversion It seems when you add points on an elliptic curve in sage, it immediately divides by the z coordinate if it is not zero. Since I plan on working in a finite field of a large prime, I would rather it not calculate this inverse, but I'm not sure how to stop it from automatically doing so. How do I get it to leave the z coordinate alone so as to avoid inverting elements of my field? |
