Some integration schemes are set up so that the rounding error tends to cancel out over the course of an orbit; these tend to suppress the orbital precession. For instance, leapfrog is better than a similar Runge-Kutta method in the sense that it is symplectic. | |

I never realized that rounding could have such drastic effcts. Good thing my program isn't going to involve obiting when it's done. | |
