Round-off errors in long-term tracking for the Superconducting Super Collider (SSC) with 64-bit precision (single precision in Cray or normal double precision) are found to be insignificant. One-turn Taylor maps are useful for studying the beam dynamics of the alternating gradient synchrotrons and can potentially be used for fast long-term tracking up to 100 million turns for the SSC. 14 refs., 2 figs.
