Instead of Normsdist(z) function use

  1. Use this approximation
    for the cummulative area under the Normal curve

    =0.5+z*0.389377141853663+z^2*1.08529111489983E-11+z^3*-0.0513483086730824+z^4*-1.50619079729924E-12+z^5*0.00335208405946254

    where -2.5 < z < 2.5

    can use them for only the above Z=standard Normal

    this way U can use it in other Non MS software
