Abstract
Two numerical schemes of rotational neutron star based on general relativity，hartle code and Butterworth and Ipser′s code (BI code), are introduced and discussed. The numerical results of the two codes with different equations of state (EOSs) are compared, and the results indicate that most properties of rotational neutron star with different EOSs and different numerical schemes are in accordance with each other.
