#include<stdio.h>
#include<math.h>
void main()
{
double NormDistFunc(double x)
{
double x=(x>=0?x:-x);
double a[]={0.0705230784,0.0422820123,0.0092705272,0.0001520143,0.0002765672,0.0000430638};
double m=0;
double erf;
for(int i=1;i<=6;i++)
{
m=a[i-1]*Math.Pow(x,i);
}
erf=1-Math.Pow(1.0+erf,-16);
double phi=(x>=0?0.5*(1+erf):0.5*(1-erf));
return phi;
}
}
