The present author proposes a compensation algorithm based on the principle of replacement of integral region and gives some practical approximations to the normal distribution and its inverse as follows: Y_m(u)=[1-4/π sum from i=1 to m θ_ie~(b_iu~2)(1+c_mu~4)]~(1/2)~2Φ(u)-1, m=1, 2, ,… with maximum error less than 9. 3×10~(-5) for m=1 and 4×10~(-6) for m=2, u=[u~2_0+d_1u_0~4+d_2u_0~6]~(1/2), u_0~2=-π/2 1n(4p(1-p)) with maximum error less than 1×10~(-4).
